I guess, because we don't really know all the dynamics with this family, we should maybe look at MR was doing the best he could under the circumstances. We can talk and talk that he was trying to cause her pain, that she doesn't trust him etc.
In actuality we don't know how this family communicates. Not really. Quite frankly, as much suspicion surrounds MR, he has behaved pretty well when speaking about ER.
We don't know (at least I don't) that MR never responded or tried to reach out to her.
He certainly strikes me as depressed, and I guess we don't know for how long, if that's correct. I don't know. MR sure has my hinky meter up.
Hope this makes sense cuz I'm kinda rambling.
