Panel 2: "Demonic flesh-eating roach people". Jeez, Lynn will stop at nothing to vilify modern movies. Or rather, to mock what she thinks movies have come to. And again, I think the dogs are simply reacting to April's panic. If a dog really thinks there's danger, they won't let you restrain them.
Panel 3: Yeah, but now you're TRAPPED INSIDE! MWAH-HA-HA!
Panel 4: Oh brother. So it's just about her fear, not about any real threat. Well...there's still a chance for redemption, I suppose, if she faces her fears and conquers them and all that jazz. Still...puke.
