6. Saul offers to write Mike's will
He doesn't take him up on it, and there's some significance to it -- between now and Breaking Bad Mike does set up an 18th birthday trust fund for his granddaughter Kaylee, which the DEA finds out about and likely seizes all of his money from. Would the will money have been seized? I have no idea, but... maybe?
7. The diner we see Mike in? Won't be the last time he goes there.
This is the same diner Mike later meets Lydia at in "Madrigal" where she hands him a list of eleven men who were on Gus's payroll and suggests Mike kill them before they can implicate either of them. Mike shoots down the idea, vouching for his men and leaving Lydia helpless, panic-stricken, and still super butthurt that the place only offered Lipton iced tea (WHAT IS THIS, PRISON????).
