I think I've said this plenty of times, but! For Kanae her best friend in the Scions is Urianger-- despite ARR being "what is he even SAYING" and late HW being "...can I actually trust you though?" she both learns from Y'shtola a bit in StB and sees in ShB that they actually have a bit in common. Those lectures on the language of the Fae? Kanae is all ears-- horns. You know.

For W'htal he immediately felt a connection with Tataru-- part of it was that his best friend ("best friend") in Kugane, Kinu, is also a lala, but also despite her initial impression, he could tell she was capable with coin. He appreciates that, and even now post-6.0 is more than happy to help with her new business empire haha
