thank you! i love yours, i've never seen him before but i'm a fan. so one idea was half brothers, maybe they share a dad? el knows literally nothing about his biological father so it would make sense. we could come up with how they came to figure out they're related. OR they share a mom and she either gave both of them up, or had a sister or something raise luca. whatever you would feel more comfortable with. with that i was thinking she confessed in a moment of sobriety to one or both of them about the other. ANOTHER IDEA would be cousins on his mother's side. same sort of situation. she tells elliot hey i have a sister and she has a kid/kids that are your cousins if you ever want to know more about your biological family. sorry if this is super rambly i hope it makes sense
