Hey, thanks so much for playing, I'm glad you liked the story!
[SPOILERS]
Oh man, that was a bug! I had a statement in there changing a variable to help me debug, and forgot to comment it out again before submitting. Thank you so much for bringing this up!
I've just updated the submission now to fix that, so now it'll be possible for Dr Laine to believe you if you choose the options that annoy him the least :)
