micki's a little younger than her at 22 and only moved to san fran a couple years ago, but i'm sure she's visited wyatt often so they would have met back then? micki can be a little bitchy herself and sarcastic a lot of the time. i'm betting they could have even rubbed each other the wrong way at first and then at some point things just kind of fell into place for them? i can see micki feeling a little insecure initially when they got together until she was confident that jordan wasn't replacing her in wyatt's eyes or anything if that makes sense.
