Oh now that's a great idea to get a cure any of the spawn who may want it.
In my last comment, I realize I was a bit vague. I didn't necessarily mean something to shield him with on the docks, per se.

If you romance him, in the scene after the docs, you can tell him you'll help him find a way to walk in the sun again. And he really appreciates the possibility and expresses that's an adventure he's interested pursuing alongside Tav.

That's what I was referring to. He wants a solution so he can walk in the sun, it doesn't inherently mean he needs/wants cured.
