Their marriage is built on material goods. This is usually a sign of a not-so-healthy relationship. Ergo, there will eventually be a bitter feud and, ultimately, a split.
- The Paradoxes that Phil almost causes were meant to happen and ultimately be resolved due to the STL.
- Phil is not his own ancestor, but his own cousin. We meet one of his ancestors nothing is changed due to the STL. Its entirely possible that Phil had cousins Lloyd's cousins as well, growing up that were in actually he and Keely's descendants.
- This is created by Phil revealing himself to his own ancestor some years later after he and Keely get married. A cover story is created where Phil is passed off as his cousin. This is done to conceal from himself that he time traveled thus keeping the Timeloop stable.
Theory 2: Seth hangs out around Phil a lot in season 1. He accidentally found some of his time travel stuff and transported back to the 80s and become younger where Constance, wanting another child, took him in. She died his hair so he could look more like her actual son, named him Tate because he was too young to remember his name/care, and raised him as her own. When he's growing up he has 2 lives in his head which would be too confusing to almost anyone. He still had his previous intelligence (ex: Poetry and books about birds). From remembering 2 lives and everything at home or his tough 2nd upbringing combined with memories of everyone taunting him as a nerd in his 1st upbringing made him go mad/confused, thus the shooting and madness.
