You cannoooot tell me there isn't resentment here.
Oh, his face speaks volumes. I find it interesting when Deli starts talking he immediately looks at the camera to see where it is at. He definitely doesn't like the camera and from what I have seen, it seems like he puts on an act whenever he's being filmed or forced to be Deli's tripod. His over enthusiasm, his mannerisms, talking about random, weird things to break the awkwardness. This is not a man who enjoys having his day to day life recorded.
Just the way they are talking in "We are renovating", while Deli is packing her clothes, James seems a bit miffed and Deli just straight up walks away while he is talking and ignores what he is saying. I can imagine he just wants to get the clothes packed and has to put up with Deli going through all her clothes, trying them on and deciding if she wants to keep them or not. Look at his face when she mentions her good will bag and the bin she's keeping. He looks so exhausted and defeated. I wonder if he thought he was out of frame?
Then the next day, he's all smiles and enthusiastically waves at the camera. Just looking at the way he waves and his over enthusiastic tone, it looks like an act to me. People's true feelings come out during times of stress and tiredness, when they can't keep the act going. Food for thought.
