In the mine, Archie catches up to Henry. He's peering through a crack in the rocks where he found the glass. "There's something shiny down there," he says. Archie pleads with him, says he's afraid for him. "Because you think I'm crazy?" Henry snits. "No! Because we're in an abandoned mine... and there is no way out!" Henry has the sense to look a little bit scared.
Outside, Pongo barks and hangs out with Ruby. Construction workers try to clear some rocks away from the entrance. Another tremor shakes the earth. Regina yells, "Stop! Stop! You're making it worse!" Heh. I thought she was shouting at the ground at first, but she's shouting at Emma. They get into a pissing match about whose fault it is that Henry's down there. Regina, near tears, finally snaps, "Oh, please, lecture me until his oxygen runs out!" That gets Emma to focus and agree to stop arguing.
In the tunnel, Archie and Henry can hear Pongo barking outside. They move toward the sound and find an old elevator.
Outside, Regina and Emma begin hatching what may be the worst rescue plan ever. "We need to find some way to punch through the ground," Regina says, "we need something big." From nearby, Marco pipes up, "Explosives!" Instead of immediately and unequivocally rejecting this idea, Emma and Regina look thoughtful.
Archie and Henry are just starting to turn a crack to get the elevator moving when Regina gives the command to set off the explosives. Everyone has moved, like, a hundred yards away and have taken cover behind trucks, because they obviously realize how dangerous this is to them, and yet somehow don't realize how dangerous this is to Henry and Archie. What if they're right on the other side of the entrance? What if they get crushed by rocks? What if they get swallowed up by one of those fireballs I keep waiting for? I can accept tiny blue fairies and magic potions, but have a tiny bit of logic on the "real world" side, please. Anyway, the blast sends rocks and dust billowing out from the entrance and drops the elevator to the ground. Sheriff Graham stands around looking pretty. Emma runs through the smoke to the entrance and reports back that it didn't open. "Then what did it do?" asks Graham. The question is so profound that they have to take a commercial break to think about it.
