My Card.

Rex and June aren’t going to let the over-powering smell of chlorine and bleach keep them from entering an empty school without permission. No, they’re too brave to let that stop them. In panel three I’m waiting for Rex to say, “Don’t worry, my card will protect us.” I might even have been tempted to believe it if it didn’t look like he had it hung on a shoelace around his neck.
I do like how in panel one it looks like the guard (at least, I think it’s a guard) is pointing a gun at them, though I’m sure it’s just a finger. The guard also seems to have purchased the child-sized masks for the dangerous task of guarding an empty school. Well, that or he and the other guards are recreating Mortal Combat fights in the gym with dodge balls, climbing ropes, and whatever else they can find in the gym closet. Considering how it looks like he’s starting a power up move in panel two, I’m starting to think the fumes could be getting to him, even with the mask.
