MEMORIES FOR ROUND 2:
1) Killing River. She won't recognize the girl's face or know her name, but she'll recall headshot-ing her at the end of what was obviously a fight between them, as well as all the reluctance and negative emotions she was feeling at the time.
2) Albert Wesker. She'll remember his name and face, but nothing else.
3) Tifa Lockhart. Same as above.
4) Her first meeting with Cid Raines -- but she'll only remember her part of the conversation for the most part. Namely how she admitted to unintentionally hurting innocent people.
5) Punching Chris in the face in the second battle. Or, rather, "punching some big guy in the face."
