I have not watched the show. But from what ive heard you make a good point. They took control of the commonwealth so it's safe to say he's just chillin there killing raiders with all the other people in the BOS at the airport

Then again I have no proof

Would they really just leave Prime in Boston though? He seems too valuable to be left behind..

The Minutemen ending can still be canon

I'm curious where Arthur Maxson is becaus regardl of MM or BOS Ending, I can't imagine him in anyway just being like Kells "Take the Prydwen to California" without him being present hboess they're waiting til alter to show him. Only way I'd buy that is if Maxson has a improved vessel with the likes of a Prydwen MK II with the BOS drastically budding their base, or establishing a new headquarters in the Commonwealth aside from Cambridge Police Station & The Prydwen.

@Fallout Fazbear I agree because they're both dealing with The NCR-Brotherhood War, in addition to taking down an Former Enclave scientist without knowing if he's traveling alone or with Enclave remnants. I can't see Maxson sending his prized vessel to assist the Western Brotherhood and not going all out showcasing Liberty Prime as well. With it being the case of its power destroying the institute. It's like showing off a sword vs a sword and a shield
