problem here is that that's a comic and not the game.
It was officially produced by Value to branch both the gap between
Portal and
Portal 2, and give some backstory to the facility. It is canon and taken as such.
Or are you saying "
It's not in the game, so how would you expect me to know it? D:" In that case, thank you for admitting you aren't informed enough to make comments about how much storyline
Portal has.
