Luke shrugged and said, "I've spoken to Tim. Jeff and Karen only need to give the fake files to Tyrannosaur and then leave with the money. The arrest won't happen until after they're gone."
Selina immediately got it.
In other words, this was a fishing operation, and Jeff and Karen were just throwing out the bait; they wouldn't be the ones to reel in the line.
They didn't need to do or think anything else.
This sort of operation was still dangerous, but you didn't have to be a super pro; it was fine for Jeff and Karen to look a little nervous.
As a regular couple that was about to sell MBI company secrets, they had every reason to be nervous.
When Luke and Selina got to the hotel, they parked and leisurely made their way up through the underground carpark. Selina casually asked, "Why are we going up from here?"
Luke said, "Tim and Natalie are on the hotel roof, so naturally, we can only enter through the carpark."
