Not quite sure how close Mimi and Salem are at the moment, so I don't know if she'll know about Mr. Ex. But random interaction is definitely a way to go!
Any friends of Micahs will (hopefully) be a friend of Salem. In that annoying 'omg my little sister won't leave us alone.. okay she's pretty cool but she really needs to get her own friends' kind of way.
Ahaha I love that picture. I would love cliche cuteness! I'm obsessed with Teen Wolf right now. They should definitely have a run in or something, probably at Best Buy because I've just decided her laptop broke in transit and she is sooo distraught. She can't live without it.
