GLaDOS suddenly decided that bathing in the blood of past test subjects would be a great idea for Halloween. She had enough of it around so why not?

Her first realization was that this was very unsanitary. Second, it was surprisingly comfortable and warm. Third was the question if this could possibly short circuit her. Lastly, was how she was going to get all of it off of her after Halloween

Chell strode into the main chamber with a package of spiderwebs. She thought that even though GLaDOS was quite scary by herself, it could add a festive touch. And as long as it didn't destroy testing, their newly found non-enemyness wouldn't be destroyed.

She almost dropped the package when she entered the room though. The mainframe was covered in red blood, dripping and sliding down it to form puddles on the floor. The AI was turned away, focused on something on a metallic table that was covered with white pristine cloth. Blood drops were strewn about the cloth though, and a knife was currently being finessed by a claw from the ceiling.

Chell gulped and ran out. The AI was perfectly fine for the terrifying holiday.

GLaDOS turned at the sound of footsteps behind her, but found nothing. She did her equivalent of a "who-knows" shrug and continued with the deemed scientific dissection.
