In ruin it was confirmed that the canon ending of security breach was the princess quest ending, but that does not mean Gregory hasn’t seen burntrap as shown in the comic page in ruin. Both princess quest ending and burntrap ending happened and here’s what I think happened. First Freddy and Gregory went down the elevator to the burntrap room, though burntrap was never taken by the blob. Instead the blob ended up tunneling out of the pizzaplex as seen in ruin it went up the shaft and burrowed into the wall. Gregory and Freddy had to run from burntrap and crossed paths into the mimics lair shown by Gregory’s backpack before you enter in ruin. They escaped through the same elevator that cuts in ruin from the mimic but burntrap didn’t make it and got trapped with the mimic. We know burntrap entered the mimics lair in some way because you can see burntraps claw marks on the wall. This may mean that burntrap is the mimic but I don’t actually think this because burntrap has a simillar endo to the mimic and claws but burntrap is covered in flesh and we know that flesh covered burntrap is real because in the comic page in ruin that’s what we see and it’s unlikely that Gregory made that up. Gregory would have entered the mimics lair at some point to seal it up and create m.x.e.s. After going up the elevator that’s when the princess quest ending happens. This theory still leaves a lot of questions about what happened to afton with the Mimic but I think he got caught by the mimic but his remnant lived on because “he always comes back” his remnant would have been spilled on the floor somewhere holding his memories and in a crumbling pizzaplex, it’s likely that it could have collapsed where the remnant combined with everything maybe from the sewer or something creating afton amalgamation.
