I think Mescal performance is deserving of his Oscar nod, just a quick glance and body movement tells you all you need to know on that character.

I could be totally out of my depth here. It always felt looking at Calum , that Sophie's mum probably dumped him and that his family was everything to him. When he's in conservation with her on the phone, you just tell the man's heartbroken to see that she's moved on to someone else. You see moments of recklessness from him that shows that he's on the edge.

That Sophie is probably the only person he has left that keeps him hanging on, and that once he sees that she's growing up and growing apart from him throughout the holiday, that it's the end for him. And not knowing it's clearly effected Sophie that she needed him as much as he needed her. That's what I read into it and it's really heartbreaking.
