As far as I know they don't have any other plans for him. After the Institute is destroyed he returns to Boston Airport and stays there patrolling the area.

"Companies like Arcjet are evil and caused the downfall of humanity yada yada"

"Hey guys let's build a giant robot of doom that throws litteral mini nukes at the first radroach in range, we'll be the only one allowed to control it and use it against those that we don't like"

The good guys™

He's Probably still at the airport, waiting for a new purpose...

They could always string drying laundry from/around him .... :)

@Shenachie That's a holy definition of "Where Are They Now?"

I think he's still trying to find commies
