Corrected entry: Agent Ferris said Liz should be at least 2 minutes alone, before putting the pill in to the orange juice, or else Cris sees it. Wouldn't Cris see himself passing out from the drink? (He saw the train coming earlier in the movie.).

Correction: The drugs take five minutes to knock people out. Cris can only see two minutes in advance. He would see himself knocked out by them, but not before he had already drank the juice. At that point there would be nothing he could do about it.
