So.... Are you suggesting that Alice is in Conrad's pocket, and that 1) Maeve's leaving the glass, 2) Conrad's putting his cigar butt in it & 3) Conrad's wink to unleash Seraphina's questioning to offend Alice and give her an excuse to get said items were all pre-planned so that Alice could be caught stealing DNA evidence? If that's the case, who's the rat? And to what end is Alice cooperating with Conrad and Maeve?

This is definitely an interesting theory and one that I hadn't thought of, I can't seem to think it through to its logical conclusion.
