I don't have a platform but I'm gonna say it before anybody else does - asriel is a rainbow baby and ralsei is toriel's previous miscarriage. asriel for one has rainbows as his gimmick, and ralsei has fire powers, STRONGLY resembles asriel, he's an "impossiblity", doesn't follow the same rules as other darkness, (doesn't petrify, appears in dark worlds despite not having a lightworld form or being in Kris' pockets), why he has otherworldly knowledge, why his name is a reshuffle of asriel's name (toriel probably wanted asriel to be the name of their first son, so oops) etc RALSEI IS A GHOST. also asriel has always had a dead sibling from the get-go thematically (chara) and this is a parallel story so it would 100% happen again
thanks for coming to my TED talk
