You hide as if A-150 is gonna spawn and head towards to the main room your in, you see that A-150 stops at the center of the room and then spawns its clones. Some of the clones were PXI-150, TLP-150, THI-150 or whatever.. However you saw one clone, it seems to be sad.. And somehow, it heads towards to your hiding spot.
