flowerings:

PETER: Olivia… I’m sorry.
OLIVIA: You weren’t yourself.
PETER: It’s lucky for me that you were.
2×13- “What Lies Below”

WALTER: I don’t know what happened, but this is not you.
3×11- “Reciprocity”

I don’t think it’s a coincidence they used such similar shots and dialogues in both episodes. The fact that Peter wasn’t acting like himself seems to be a theme in these. Now what makes me curious is if Olivia being herself will help Peter once again.
