>>90767891>>90768056Oh, that chapter. Yeah, that was confusing. You have to put it in context with what was on Mike's mind leading up to it.
- In "Dial Tone" Mike had a nightmare involving being guilt-tripped by Lucy, and being ignored/abaondoned by Sandy.
- He wakes up traumatized, only to be made worse by desperately texting Sandy and getting no response.
- This triggers Mike to remember this happening before, and running to Lucy for comfort, showing one of her rare moments of selflessness.
- We move on to "Table For One", Mike is shown zoning out of everything happening around him.
- He bumps into Madison, and yells "Lucy's name", then later tells the group he had a nightmare involving Lucy. Both cases showing it's the "Lucy" aspect that's really sticking with him here.
- Skip to the end, Mike leaves everybody, sits by himself and quietly says "Happy Birthday"
Given context that his mind had been about the Lucy nightmare all day, and the fact he specifically recalled a memory of her being there for him at his lowest point. He's likely feeling guilty about how he actively ignored her on her birthday, and retroactively saying it now.
