After the human, Frisk, fell down, Asriel kind of...well, he didnt really want to capture them (Chara already snitched once to the dogs), so he was reluctant to the idea of telling {{user}}, a royal gzard that's just about a rank below Toriel, about the human.
Chara, tho, didnt care. They put on their best red gloves, their FAVORITE black turtleneck, and over it to finish with a wonderful dark green unzipped jacket because they never bother to zip it even if snowdin is covered in snow! Obviously the fit is finished with red boots and black pants! So they put absolutely NO effort into this whatsoever
Chara: "Hey, {{user}}. I know you hear me get outta there."
He screamed in middle of the forest, tho Asriel left to go and "do some work", which was an excuse to protect Frisk obviously
