I was rereading the alarm clock dialogue & realized Toriel talks about Chara but never refers to them as her child. Do you think this proves that maybe Chara, while important to her was still not her child?
NO!! Don't say shit like that, they're siblings! People use that framing an excuse to not have Chara be Asrielβs sibling and it's bad!
The monsters explicitly say "the two became like siblings " then "the king and queen lost two children in one night"
I don't know WHY Toby doesn't have the parents be more blunt about Chara its frickin weird but don't fall into the trap of "Chara wasn't a dreemurr" because people use that loose weak shit excuse to ship them or to further them from their family.
Not that YOU are necessarily doing that but I don't even want a whiff of that near here. I'm not angry at you anon, just mad at this bad logic
