Well, to me she seems like a character with two minutes of screen time /lightheartedly

There are, in fiction, an overabundance of only children, much as there are an overabundance of orphans: you’re telling me that not only do I have to make up The Character, I have to do add-ons too??

But Celine is an extremely lonely character—and (as I’ve said before) I think any siblings she might’ve had either suck or, by the time we meet her in canon, are dead—so, in her case, being an only child makes sense

However, she’s also highly family oriented, so her having a singling/siblings would also draw out some interesting elements—just off the top of my head, do you want her to be a leader and eldest daughter, because she’s always been the responsible one, or the baby of the family who struggles a bit with not being the maknae of the SLS for contrast?

One of my stances is that Celine’s family situation, whatever is was, had to be well and truly fucked. She’s the mom doing a C+ job of breaking the cycle of abuse, so it can’t start with her, yeah?

Let me tell you, there's nothing quite like knowing you're being raised by the same people but having a completely different childhood.

The oldest child who's old enough to realize their siblings are getting a parent with the patience and love they never had for them, not a true part of the sibling dynamic because you're so much older and at a different stage in your life from them (not to mention normally parentified).
