I don't think she cares about that. I think she's intended to cut him from the beginning (he's older-push him out, pretty sure she had data on the number of surgeries before she got there, etc). It would also explain why she doesn't want to fraternize with him too.
Honestly, Weber's character should retire. At this point, I don't think he adds much to the show as a central character.
On another note, I wish Kepner and Avery would get back together. I don't like Avery with the new intern. Though I was happy for Kepner when the EMT asked her out, since Avery dropped the "I'm seeing someone new" bomb.
