Just saw a commercial for the show in general that had a couple of other quick clips. One looked like Elizabeth and Philip leaning down to the floor--I assumed it was them kneeling over Gabriel on the floor. But it looked like Philip was aggressively touching him and Elizabeth was trying to pull him away, like she didn't want him to touch him.

Which could be about her wanting him to be careful not to hurt him, but I also wondered if they didn't think Gabriel had been felled by a bio-hazard thing and she was worried he might catch it.
