During Third Life there was a time when Grian got captured by Dogwarts and held prisoner. However due to the fact that Martyn saw an Opportunity(tm), he mostly used it as an opportunity to fuss over his little baby cousin/brother (depending on the au, either Martyn is biologically the older cousin but emotionally the big brother, or he's the big brother) and coddle him. Grian pretended he hated getting so many cuddles and preens and wing scritches or the overly affectionate nicknames, but Martyn knows he likes getting affection.
(Yes, yes Ren allowed it. Hell he was the one who enabled it. He even helped lol. Gotta join your best battle bro if he's gonna be like this with his baby bro.)
Gotta coddle the lil sibling, obviously!
