Doubtful, but at her age, she might still not feel right about that.
Don't know, but "So?" in response to finding that out doesn't speak well of "her."
Broadly: It could be confirmation bias, but I went back and read the first Roy-Julia conversation and then the second, and it does feel different to me. Besides the possible slip-ups, she's more aggressive, more intent on talking strategy, less willing to razz Roy. I'm leaning more toward Eugene in disguise.
