Yeah, learning companion ages would be nice. I assume Wyll is in his late 20s, Gale is in his 30s. Astarion tells us he was enslaved for 200nyears, and he was a magistrate before that so he was probably around in his late 20s early 30 himself. Shadowheart is the real tough nut though. She's a half elf so she could be decades older than we realise. Even though she looks quite young.
