Gotta appreciate Yvonne's confidence about being with Elsa despite Elsa's own nerves, definitely a perfect support for her now that they're actually together and not just Elsa flirting constantly with Yvonne
I'm sure Linda must've seen this coming between chapter 68, having confirmed that the Yvonne from that moment was from the future, and her thought in chapter 96 that Yvonne never specified a gender for her partner. Plus I wonder if Lena remembers that Elsa had a crush on Yvonne?(Ch. 78) I'm sure she'll be happy to have Elsa in the family though!
