Misty figured out Jenn's alias, which isn't too surprising. Keri has a lot of skills but maintaining alias is not one - almost entirely due to her time zone rather than anything she herself does.
I don't know what the dynamic is like between those two nowadays but the history there is BAD so I'm really leery of how this could shake out.
I'm excited to see Tina play as well. She tends to be on the emotional side of things and that can make her a frustrating ally to deal with, but she's one of the nicest and most genuine people I know, so I hope she does really well here.
