I love all of these things ♥ She and Hel could have a quiet pseudo friendship thing? I mean, she may be Loki's brood, but Nanna would still respect her and be kind if she wasn't unkind to Baldr. And Syrinx and Nanna are basically the cutest thing. Eros hahahaha oh man, she'd be :|?? most of the time, but he would probably amuse her.
omgggg Terp would looove Syrinx & Uzume, and Eros ahahaha, WELL. If he's too tricksy, she'll side-eye, but she'd still like him!
