Lacus is Lacus, although she might be kind of a lot more physically affectionate than usual. Her idea of personal space is in your lap if she likes you~
Anew will probably be a lot less unsure of herself and a lot more -- blunt, maybe. Not rude, just very very "mO_Om here have some very personal questions"
Saya will. Uh. Have to fight back murderous impulses. Volunteers who can talk her down would be so awesome. It's not my fault okay, it's canon.
Garcia has not intro'd yet but she will be herself only with more words XD
Conrad will thankfully not be in Saya's position, but he might want to drink blood from willing donors and might be semi-forward about asking... sob.
Zelgadishas plans with Saber will be letting out his inner woobie if you want to see that he's secretly a nice guy. I anticipate he will shut himself in his room for a week after.
Cross might not change much at first glance but if you want to ask him serious questions this would be the time to get honesty. but please, if you're going to ask about canon things some notice would be awesome because I may have to check with the cast, lol ongoing canons.
Komui will probably lay low because he's in enough hot water as it is. But if people want to plot with him I'm game!
In other words, BRING ME YOUR TAGS. I want them all~
