I finally saw the episode, so here are my thoughts...
Val - I don't think she's mean or unemotional. She seems like someone who is taking her role as pledge mom serious. She could be coming across like this to the pledges in hopes of letting them know that joining is serious business, especially for those women that may be there for MTV. Maybe she is just not a "bubbly" person. She does remind me of Coral too.
Meena - She should have followed up on what happened at the meeting, either by getting with Val beforehand, or by talking with her pledge sisters afterwards. I don't think she will last long.
On a lighthearted note, I thnk Janelle looks like Samantha Mumbo and Matt (from FL) looks like Jack Black.
So far I think SL III is interesting......
