The Off Topic section is not meant for discussing Cookie Clicker.
If Cam got to rant about Game Theory, I can get to rant about Underlab.
I haven't even watched the video and I can already tell that most of this is just pulled straight from their anus. None of it is canon if it didn't come from the game or Toby - it's not "everything you didn't already know" if it's not true and canon. It's "everything you didn't already think was true." And it's probably not right from any stand point - the closest they'll probably get to being correct was someone possibly having an AU sorta like this.
I can also tell from the thumbnail alone that this theory is just meant to be edgy and ruin Alphys as a character for many people by feeding people lies about how she injected Determination into herself or whatever the unholy fuck. Fuck these guys.
