You know James would be all “mom, me and sirius are starting a gang”
And Mrs Potter would ruffle his hair and say “that’s great, dear, you want some cookies and juice for on the road?”
"Definitely. Also some sandwiches, please."
I bet that Sirius Black always crawls into bed with James Potter when he has nightmares, but one day he had a nightmare and tried to get into bed with James only to find Lily Evans there because she had a nightmare. "What do you mean you have to take care of Lily? Wormtail, do you hear this? This is outrageous. Moony, fix this."
