Sage Briarstone's Links
Sage never had roommates before Hogwarts, so she didn't know what to expect from her roommates. Despite that, Sage and Isla have grown to be friends. Sage appreciates that, while she tends towards sarcasm, Isla doesn't try to put on an act or pretend to be somebody she isn't. She admires Isla's reflex to leap into action when it comes to things and people she cares about, from defending her friends to throwing herself into learning about things she's interested in. Sage has starting taking Isla's cue in making friends and being more willing to talk to people she isn't as close to. Despite being bad at most social cues, Sage has gotten used to her roommates' mannerisms and patterns, which she finds comforting. She doesn't bring it up if she notices Isla trying to brush off her emotions, especially if her Thaumaturgy gives that away, but she still tries to help out indirectly and attempts to make her day a little better.
At first, Isla was pretty unsure if she would be able to connect with Sage (given that she is a bit of a fool). However, after rooming with her for a year, Isla has become quite fond of her. Isla admires Sage's intelligence and friendship, and she's very grateful they're friends. Normally, Isla wouldn't care about the house cup but because of Sage's desire to win, Isla makes sure to take caution if she misbehaves. Sage is one of her study buddies that actually takes it seriously (especially because Isla tends to drift away from the topic if she isn't interested). Since Isla is a bit of a tsundere, she wouldn't ever admit she's very protective of Sage. If anyone ever tried to hurt her comrade, Isla wouldn't hesitate to hex them. Hopefully Sage doesn't know that though.
He escaped during DADA but she IS out for blood and WILL get revenge.
