1. Will had a complaint about the Institute's television.
It's cute how polite he is, even when he's pretending to be mad.
2. Dom ruined the perfect group photo.
If we were that close to Matt, we probably wouldn't be able to resist hugging him either.
3. Alberto had the best seat in the house at the Vampire club.
Just chilling on a balcony, like the incredibly suave man he is.
4. And later, he rehearsed the epic fight scene between Simon and Quinn.
We've never seen Simon be so badass before.
5. Check out this slow motion video of Chad's stunt:
We don't know why they're so shocked at being filmed -- isn't that their job?

Eileen Li plays Aline Penhallow, who arrived at the New York Institute to try and find her long lost cousin.

We don't even want to know what they've been up to.
9. Emeraude took a peek at the shot.
10. Will did a convincing impression of a sad statue.
If Will just grew his hair out a bit, the resemblance would be uncanny.
