Yeah Temperance is an actual name, so while I don't think it's very common but it does float around sometimes!
Oh he is a bit sad honestly, he's just a nervous kid! Very shy, but don't worry his big sister is very good support. I like writing siblings who have a strong supportive relationship, as someone who is best friend is my own little brother! (He's not a kid though lol he's only two years younger than me, we're very much like twins now)
She doesn't want to miss her Blue's Clues! ... Or whatever kids watch now
