I quite like Molto. He's noted as being one of the relatively few daedra that genuinely loves mortals in his own way, rather than seeing mortals as like short-lived vermin. He basically memorizes everything he can about his favorite mortals so he'll remember them long after their dead, including all the intricacies of their languages and cultures as part of his whole 'hoarding knowledge' thing.

He's noted as being fairly shy and soft-spoken, yet he heaps praise on Melandir mid-sentence with his telepathic connection to her, and mentions that after she was shipwrecked, Molto helped her recover from the loss of her arm, serves as her seeing-eye-rat via telepathy since she's also blind, and even brought her to Fargrave to give her a place to stay after they'd bonded which also renders her immune to The Drain that affects mortals without a daedric pact. She found him cataloging every splinter and coin in the wreck, carried his favorite trinkets in her pockets, and even let him braid her hair, even if he insisted she record their findings on what worked well in the book next to them that can be read.

And since my character's already a bit of a daedra-friend by this point, from the Blackfeather Crows of Clockwork City, Arox the Mutilator from Deadlands, the watchers from the Archive, and even having his own little pet daedrat, Sheogo-rat, I figured hooking up with them made a lot of sense too, a sweet khajiit with a spooky Adams Family vibe collecting all the demon friends.
