(01:00:20)

Continuity mistake: When Kate figures out the '60659' mystery, in the background you can see Sasha laying on the floor dead. Her hair is covering her mouth, but in a later shot, when Kate takes her necklace, her hair has moved to covering her eyes. (01:21:35 - 01:22:30)
Continuity mistake: When Kate figures out the '60659' mystery, when she looks at the watch you can briefly see it reading 6:06:15, then in the next shot, the watch is now reading 6:06:02. (01:21:40)

Continuity mistake: When we first see the colonel, he grabs the suitcase to examine it. In the far shot, you can see that the handcuffs are on the far side of the handle, near his body. The next shot is a closeup of the suitcase, and the handcuffs are now on the opposite side of the handle, away from his body.
Continuity mistake: Just after Jerry writes the number 4 on the room where he meets Kate and Sasha, they cut to a far shot as he and Kate converse. The spot where he wrote is visible and the marking is gone.
Answer: They sent the agent in to retrieve some sensitive information from the blind girl. The girl hid inside the hypercube as she knew they wouldn't come after her and by the time they figured out where she was it was too late to stop her and so they sent the agent in. They shot their own agent as the information she has is that sensitive that they can't let anyone know anything about it (even the fact that it exists).
