,,,it’s possible that Mia did, indeed, become very attached to Mickey. Just as she considers Maggie her surrogate mother, maybe she also felt the same way about Mickey. After all, we only see these people for an hour a day. I’m just saying, it’s not out of the rhelm of possibility.
I agree it’s a shame Lucas won’t be around for Maggie to lean on. It would be a chance for him to return all Maggie has done for him. I know there are rumors of Maggie falling off the wagon but I would think now would be the time (if this is true) rather than later. I believe her pain is the most intense right now. But I could be wrong.
