Shep is talking now. He's such an idiot! Other stations reported why there was only a puff of smoke when they detonated the package. That's because they only wanted to open the package, not detonate it. Shep thinks that because there was only a small puff of smoke that there must be nothing in it.

This doesn't make a lot of sense to me! "It's okay. Don't worry! I'm just gonna blast open this drum of gunpowder with a cherry bomb. Don't worry!"
