It was a choppy episode in general. I went back and watched last week's and I really had a hard time figuring out visually what was going on in that warehouse or in the revolving door.
Others have pointed this out, but the show definitely suffers when it's trying to juggle too many disparate characters/storylines at the same time, but then that's also when the plot moves forward most expediently. That's the curse/blessing of having them all together in the same town instead of separated.
