From Heroes Wiki
Danko meets Alena at her home.
They kiss on her front porch as he leaves.
Matt Parkman sneaks into Alena's home to get revenge against Danko by killing his closest friend. Matt can't kill her and convinces her he's a friend of Danko's instead. After a brief conversation, Matt tells her he's going to take her to see who Danko really is.
Danko tries to call Alena to apologize for his lies and convince her he's really the person he pretended to be, but Alena is ignoring his call. She leaves her home and gets into a cab.
