¶1Appeal of Plaintiffs
¶2Plaintiffs argue that the court erred in granting the defendant’s motion for a directed verdict. We agree. At trial the plaintiffs presented evidence that established a prima facie case of negligence on the part of the deceased. Thus, with no further showings, plaintiffs would be entitled to go to the jury.
¶3In this case defendant countered with testimony aimed at establishing the affirmative defense of sudden incapacitation. In North Carolina the burden is on the party asserting sudden *111incapacitation to prove the defense by the greater weight of the evidence. Wallace v. Johnson, 11 N.C. App. 703, 182 S.E. 2d 193 (1971). In Cutts v. Casey, 278 N.C. 390, 180 S.E. 2d 297 (1971), the North Carolina Supreme Court held improper the direction of a verdict in favor of the party with the burden of proof where that party’s right to a judgment depends upon the credibility of his witnesses.
¶4In the instant case the testimony of Mrs. Garrett as to when the sudden seizure occurred is an essential cog in establishing the affirmative defense. As the wife of the deceased and named defendant in the lawsuit, her credibility is definitely in issue. She argues that since her testimony was uncontradicted, it was positive evidence conclusively establishing the sudden incapacitation. This argument is not persuasive. “It is quite clear, however, that . . . evidence is not necessarily conclusive because it is uncontradicted. It is still for the jury if reasonable men may differ as to its truth or if conflicting inferences may reasonably be drawn from it.” Cutts v. Casey, supra at 421.
¶5As stated above, the credibility of Mrs. Garrett and her testimony is for the jury. Further, a question of fact is apparent from the record. Defendant’s evidence shows that seizure occurred first, thereby causing the accident. If the jury believes this evidence and defendant’s other evidence concerning the prior good health of the deceased, the logical inference is sudden incapacitation. Plaintiffs, however, offered evidence tending to show that the deceased was suddenly seized at or just after impact. If believed by the jury, this evidence could lead to the equally plausible inference that the accident was caused by the negligence of the deceased and that the sudden trauma of the impact induced his seizure. The resolution of this question of fact along with the credibility of the moving party were for the jury to determine; therefore, the directed verdict for defendant must be reversed.
¶6Appeal of Third-Party Plaintiff
¶7In her third-party complaint the defendant, Mrs. Garrett, alleged that Burns was concurrently negligent in that:
“ . . . she operated said vehicle at a speed which was greater than reasonable or prudent under the conditions then existing in violation of General Statutes Section 20-141; she operated said vehicle without keeping a reasonable and *112proper lookout; she failed to keep her said vehicle under reasonable and proper control; although she had ample opportunity to do so, and although she knew or, in the exercise of reasonable care should have known, of the risk of a collision and the necessity to take reasonable action to avoid the same, she nevertheless failed to slow her vehicle, or to turn it aside, or to take any other action whatever, as she could and should have done, to keep her said vehicle under control and to avoid a collision.”
¶8She argues that the trial court erred in directing a verdict for third-party defendant Burns in that there was sufficient evidence from which Burns’ negligence could be inferred. We agree.
¶9Plaintiff Smith chose not to sue Burns. Chapter IB of the General Statutes authorizes contribution from a joint tort-feasor. Under G.S. 1A-1, Rule 14, the proper method to join an alleged tort-feasor is by third-party complaint, as was done here. The relationship between the original defendant and additional defendants is the same as under the former statute, G.S. 1-240. “The original defendants are as to the new defendants, plaintiffs, and as such required to establish their right of action.” Norris v. Johnson, 246 N.C. 179, 182, 97 S.E. 2d 773, 775 (1957). Thus the burden of proof is on Garrett as third-party plaintiff to prove the concurring negligence of Burns as third-party defendant by the greater weight of the evidence.
¶10In this light Burns’ motion for a directed verdict is one against the party with the burden of proof. The evidence must therefore be considered in the light most favorable to Garrett with all reasonable inferences therefrom drawn in her favor. Jones v. Development Co., 16 N.C. App. 80, 191 S.E. 2d 435 (1972). As third-party defendant, Burns argues that Garrett introduced no evidence showing negligence on the part of Burns. The scope of evidence that can be considered, however, includes not only the plaintiff’s evidence but also that presented by the defendant to the extent it clarifies the plaintiff’s case. Jenkins v. Starrett Corp., 13 N.C. App. 437, 186 S.E. 2d 198 (1972).
¶11From the record it is apparent that the following facts were evinced through direct and cross-examination of Burns and other of plaintiffs’ witnesses. Burns, through interrogatories, indicated that immediately before the collision, she noticed the Garrett car weaving. Both cars were travelling between 20 and 30 miles per hour. Plaintiffs’ witness Williams testified that both *113cars were travelling side by side until the Garrett car veered into Burns’ lane. Further, plaintiffs’ pleadings and evidence show that their injuries occurred not at the impact with the Garrett car but from the subsequent battering as their vehicle jumped a curb, proceeded down an embankment, and impacted against a tree. Plaintiffs’ witness Williams noticed no skid marks on any part of the road traversed by the vehicles. Plaintiffs’ witness Hall recalled no sounds of tires skidding or squealing. Burns could not recall braking her vehicle. From the point of impact on the boulevard to where the Burns car came to rest was 106 feet.
¶12From these facts, taken in the light most favorable to the third-party plaintiff, there is sufficient evidence for the jury to infer negligence on the part of Burns. A jury could logically conclude that prior to impact, Burns had the opportunity and did in fact observe the Garrett car weaving and that she failed to take any action that a prudent person under the circumstances would have taken to compensate for the distress of the Garrett vehicle and to avoid the collision. Further, the jury could logically conclude that after impact, Burns, by failing to brake or otherwise control her car, did not exercise the reasonable care of an ordinarily prudent person under similar circumstances. Directed verdict for the third-party defendant was thus improper.
¶13The directed verdicts for both defendant Garrett and third-party defendant Burns are reversed. This cause is remanded for a new trial.
