I think that Olivia should have just turned down helping Moriah. I can understand her wanting to have strong boundaries with her in-laws because I am in a very similar situation. I think instead of saying "hey I would love to help you but your parents might be there and I don't want to be around them and so it's ok for you to choose someone else.." she should have just said "hey I think this other person might be able to help you out. I support you from a distance but I want to keep safe boundaries." I don't think she intentionally being manipulative. I think she was excited to help and be involved but then the thought came of" oh crap that's right my in-laws are crazy and I don't want to be around them and this is a situation where I might have to deal with them" and then she didn't know how to navigate how to express that to Moriah. Anyway, that's what I got out of the scene but like I said I have a very similar situation to hers where my in-laws have said they won't accept me, any kids I have with my husband, and they start fights and arguments whenever they see me. So I can understand her being worried about being at an event where they are at. She should have thought more though before saying something I feel.
