[SPOILERS] Question about Us, from the prologue

[Gweca002]

Do I have to lobotomize Us to get them as a companion later?
I have a few playthroughs going at the moment, and on the furthest one in I found us as a summon at the end of act 2.

Because I lobotomized them in the prologue they have a debuff that affects their stats. Do I have to lobotomize them to be able to recruit them later or can I have a non-debuffed Us fighting for me?

no lobotomy needed

Can confirm I got Us regardless of whether or not I injured him.
