since they have a fairly similar upbringing, i could see her considering enzi like another little brother, if that works for you! she and elliot weren't really close as kids because he was adopted a while after she was and there's a five year age gap between the two of them. but when he was 18 and moved out, they lived together for a bit and that's when they became close and she actually made an effort to be involved in his life. maybe when they were living together, he spent a fair amount of time over there so they got to know each other then?
