I understand what you are saying, but I kind of disagree with you. My mom and I went through something similar (though I obviously didn't go on tv or anything) when my dad died, though I was 21 at the time, not a child. We have to remember that it wasn't just a wife losing hzr husband, it was also a kid losing his dad. I can kinda understand and forgive Ian's mom for how she acted when her husband died and when the whole "angel" thing started, but not now. She HAD people coming to her and Ian after the initial story, and their support helped her mentally, but did she use these opportunities to make some real friends, try to grieve and support her son in his own grief? No, she kept leaning on Ian, on the shallow admiration she'd get from people for the "angel son", made Ian carry that burden as a child and kept pretending to herself that he was okay with it when he's clearly not! Yugun noticed it so quickly, but she can't? She's not even really looking at her own child! If she broke down sometimes in tears because of her grief, I'd understand completely and would defend her, but she doesn't ask Ian to be a shoulder to cry on and do it for him as well, she makes him carry her on his back. The one that truly didn't get any support through his grief and the whole ordeal is Ian! I think that's why he loves Yugun so much, he can finally relax and just be himself with him. My mom cried more than I can recall and she asked for my support, but she supported in turn and never made me carry her completely or made me do things I was clearly very uncomfortable just for her sake. That's incredibly irresponsible from a parent, especially since Ian is still just a teenager.
Sorry for the very long rant, but Ian's mom attitude just really rubs me the wrong way.
ian's mother is so annoying but also pitiful, no one helps her recover when all she has left is her kid
