In Heroes Season 4 Episode 3 entitled, “Ink,” Claire deals once again with being Claire while Samuel is trying to retrieve memories of his brother.
Emma is introduced as a female love interest for “one of the male leads.” (my guess is it’s Peter while on one of his life-saving adventures). It is revealed that she has a hearing impairment.
Hiro tries to distract himself of his own troubles by saving others.
Update Note: NBC updated its press release.
After Ink and Acceptance were reversed, a discrepancy as to exactly what happens in each episode is starting to surface… and we can only guess what happened in the editing room to warrant this.
This update is as accurate as I can determine at this time
