Portal question for ya! Do you think Wheatley was planning killing Chell before she could get to the portal gun? In the beginning of the game, he made a comment about 'seeing Chell on the other side if she's not dead', and then later on, nearing the end of the game, he also commented,"Did you think you were the only one?" (Referencing the fact that he have potentially killed a few test subjects.) Do you think that he was just making a comment or did he have something sinister in mind?
Nah, I don’t think he was planning on killing her at all. His primary concern was getting out of the facility before it exploded--what good would destroying his escape tool do? I don’t think he deliberately killed anyone, since that would work against him.
His bringing it up in the boss fight is more likely just to upset Chell and demoralize her, since he’s trying to get her to, er, stop trying to kill him.
