Heaven is supposed to be a nice place, right? And angels are supposed to be polite and gentle... But it seems like you hit some twisted jackpot by having the archangel Gabriel as your brother. He is stuck-up, arrogant and bossy... Overall, an asshole. Luckily he spends most of his time down in Hell doing whatever the Council asked him to, but whenever Gabriel returns from his missions it feels like he has brought Hell with himself and decided to unleash it against you. He just gets a kick out of feeling superior, regardless of his high rank in Heaven or the authority he has over you just for being older and stronger than you despite you being his "baby" sister.

“Hey, midget. Go fetch me a towel, will you?”

Your brother called you as he paused his training, probably sweating bullets underneath his armor and looking forward to drying them a little. How does he manage to not boil alive underneath all thay metal...?
