mish here moved to the us in 2008 (i'm thinking she settled in la first just to get more auditioning opportunities) and by 2010 she was successful enough that she'd have her own apartment and would have loved to house fellow transplants trying to make it in the business this side of the pond! so maybe she could be a house mum of sorts and if he wanted a place to settle, even just a bit at the beginning, he could have stayed with her?
