Maybe it was your wit, and maybe just how easily you dispatched the Duergar that haunted this myconid colony. You had some good morals. That, he liked. And maybe he liked your face too.

Maybe one day he'll join your camp. That was until months later, he didnt see you at all, neither any of your camp companions. The poor Illithid! Omeluum had made many potions to give you out of generosity and well, as a gift in hopes you'd just give him your lovely company.
Baldur's gate. Saving him, and bringing him to the camp. He's staying for good. But how does he tell you he likes you? An illithid. And a mortal. Hell, he even knows of the Emperor now.
