Corrected entry: Peter Petrelli got the power to heal when he saved the cheerleader, as seen when he is stabbed by the glass from Syllar, However in this episode it shows that five years in the future he has a large scar across his face. This would not be possible as any cut he received would have completely healed.
Correction: In a different timeline, Peter loses his healing ability. Completely possible it happened in this timeline as well.
Correction: Without knowing the details of how Peter got the scar, it cannot be stated categorically that Peter would be able to heal it.
