I’ve gotten this ask maybe three times so this will be in answer to all of them. As of right now, I’ve finished the story portion of the Isle of Armor DLC and am fairly confident I know what I’m doing with these two.

Avery is most likely going to be endgame with Milo. Marigold is their daughter, but they’re not a couple when she’s born. They later do end up settling down together which is when they’ll most likely have another child, a son named Forsythe. I’m leaning towards Avery either taking over Milo’s Gym or being a Gym Trainer for Bede or a combination of both where he does one first then the other.

Klara most likely remains single. I’m leaning towards her becoming the Stow-On-Side Gym Leader and being rivals with Marnie in the classic pop vs punk battle. She’ll (faux reluctantly) babysit for Avery and Milo’s children though, and probably the BedeVic army of children as well.
