Frank Minelli has slammed his locker door one too many times, and the corner of the mirror on the inside has broken. He also keeps a slip of paper behind it reminding him of his Archives password; April compliments him on his security arrangements. April removes the mirror shard, saying she'll have to be careful carrying it around with her.
The Brave New World Airlines Shuttle 709 wreckage outside the NPD station is guarded by a laser fence. Demonstrating that you can learn everything from TV, April copies a technique from the television series MacGuyver 2200 and puts the mirror shard in the laser beam, reflecting it back and shorting out the fence so she can retrieve the AG Unit.
