Jude speaks English, Japanese, Spanish, German and Chinese a little!! he's good at learning languages and likes it very much so he spends his free time with it often, he is most fluent in Japanese since he used to live there and worst at Chinese but he wants to learn it for Qiu so he tries still
Fio just speaks English fluently but she speaks Italian at A2 level and knows a few German words too (for Tamarack ofc). She doesn't have a separate want to learn new languages and she learns Italian just because she's Italian so she feels like she has to know it (even though she never lived or went there) but gives up a little quickly 😔
