listen I know the running bit is "trinity santos peds calls to you..." but I'm actually such a huge fan of the fact that trinity is not shown to particularly like kids. she's understandably irritated by baby jane doe's crying, (doesn't she even make a comment about how "this is why I didn't go into peds.." or am I hallucinating that lol) and she makes a couple other (funny) comments that give the impression she would rather be doing anything else.
I think what's beautiful about trinity santos + kids in s2 is that she is so kind and good to them despite not having a particular enjoyment of them. softening herself when she talks to Kylie, going the distance to make sure she's safe. singing a lullaby to BJD. comforting the boy who got his fingers blown off, gentle, soothing. trying to fight against an impossibly broken system to find some other way for the boy to have both his parents and his sister at the same time, to have a chance at a better life despite the hopelessness of it.
trinity santos is kind to children and that does not make her a mother. that does not make her a peds doctor. it doesn't make her find some particular love for them. and I fucking love that interpretation way more, because so many times, media will center women around children as if it's their "calling". they motherify so many female characters. they didn't twist trinity into a motherly character she doesn't embody.
the fact that she's good to children is because she's just a good fucking person. and because inside her is a child who was taken advantage of and hurt very badly, so children are probably easier to empathize with. she relates specifically to feeling so much pain whilst being young and scared and confused. and most children have an innocence that does break down barriers and shells. trinity adapts to that communication style. you have to match a child's innocence.
anyways I thought her arc was rich and in character. she's quick thinking and adaptable, she likes the rush of traumas, "strong patient advocate", etc etc... her character isn't suited for peds. it's suited for the ER. she just has a good fucking heart. idk if I explained this very well but it was soo important to me as someone who doesn't particularly "like" kids but will always always be sweet to them because. they're just kids.
