(Provided I know the character and I actually ship said character XD)

Genn

You know, the farmer.

I don't really have a NOTP yet for the man XD
Genn & Varian could count as a BROTP for him
Genn & Mia are my OTP
Genn & Khadgar is my second choice pairing XD (or even Varian/Genn/Khadgar) cough

tho I wager NOTP's would be any other family members that aren't his wife or Anduin.. and no Undead

cause yes Anduin is very much like a son to him good god XD

.... anduin

I haven't really thought of any real NOTP's for Anduin either tbh, tho I suspect the same caveat of no family or Genn applies here lol
Anduin & Game!Khadgar could be a BROTP
I don't really have an OTP for Anduin per se.. but I have shipped him w/ young movie!Khadgar (be it AU or actual movie verse) , also with Tess XD
