I would totally go with Winterwatcher, mainly because i think they would be a cute couple. Also because they had good chemistry moments in the books from time-to-time.
Honestly, i would choose Pikenemone because he was protective of her and I think it would have made more sense. I know anemone only saw him as a bodygaurd, but if she had feeling for him, that would've been SO COOL
GLORYBRINGER ALL THE WAY! Because, HELLO! They literally had a daughter! No questions asked.
Sunlow makes sense because they really loved each other, but I think Sundrake would be valid, if there was a parallel universe where Willow didn't exist.
Slay would never work. maybe starflight and sunny, but NOT clay and sunny. It makes ZERO SENSE. Cleril was always a cool relationship ever since book 1. It would also be very interesting if they had kids.
My fav for boy dragon would probably be Winter, mostly because I love Icewings
And my fav for the girl dragon would probably be Moonwatcher because of her personality and her compassion for others.
Also, this is just my personal opinion, but these are some of the ships I thought would work. Please don't hate on my choices:
Sunnyflight (starflight x sunny) It totally would've made sense
Lynxter (Lynx x Winter) I just thought they would make a cute couple
Winkajou(Winter x Kinkajou) Okay, i know this one is weird, and now that I look at it, it doesn't really make sense. If you like this one it's fine. But honestly, Turtle and Kinkajou as a couple is so much better! just saying
Liambu (Jambu x Liana) This one is mostly because I thought that when I first read book 3, i thought they were together. Also, it would let us see more of Liana
Fiper (Viper x Flame) Okay, I know Viper died in book 4, but they did have similar personalities and I personally thought it would be funny if they did end up together, if Viper survived. I honestly think they would be an interesting couple, but not the best.
