Alright guys, somebody help me out here. I'm 3/4 of the way through SHIFT (the 2nd one) and I can't shake my mind around this potential plot hole. I must have missed something because I rarely pick up on such things in books and movies. I usually am the dumb happy type who eats up whatever I'm seeing. This one confuses me though.
**Shift spoilers below** (tapatalk doesn't have spoiler tags)
So I'm at the part where Jimmy is locked away under the server room, and somebody is trying to get in. They show up and guess 3 codes a day, then they can't try again for the whole day. Jimmy is patiently waiting for the day they get the code right. My question is, why? Earlier when his parents were hostages Jimmy was able to enter codes on his side. Why doesn't he just enter 3 wrong codes every day before they get there?
