All I could think about is what happened to the hyperbaric chamber that kept Skye alive. Seemed like it was way too convenient that the one device in the room and the nature of the gunshot wounds meant Coulson & team had to use it to get Skye to the Bus.
When they wheeled it into the SHIELD facility, I thought it would be collecting intelligence, or getting ready to explode, or some other nefarious purpose. Instead, it wasn't given a second thought. Maybe it will be one of those things brought up in a later episode.
