My two canon ones are Alicia and Lily! Als adores him and will be friendly! Lily will be happy to meet any of her sons (she'll be surprised by kid period) friends and want to learn about him!!
Jaina is his flatmate and she'll very much be amused by their living situation and flatmates!
As for the rest of mine, I think Jill wouldn't mind learning some plant stuff and she can help with watering! Lily will also help where she can!
