Is this a plot hole? If Alan Wilson killed Michelle, then he also knowingly attempted to kill Tony in the car bomb. Why didn’t Alan already know Tony’s personal vendetta and agree to meet him in S7 finale?

Apologies if this has already been discussed. I tried to search, but didn’t find any discussion on this topic. I just finished re-watching S7 and was wondering this. Please LMK if there’s another discussion on is topic if it’s already been discussed.
