Of course, Allison has to call and nag them while they're trying to outrun the magma. Meanwhile, Stark is sucking out on navigation as he can't get the instruments to tell him where the lake is. Carter suggests hitting them. Stark does. It works. Ha! Carter is always right!
The tunneller comes to the surface as the lava (not magma anymore -- happy now, Stark?) comes shooting out of the hole and into the lake. The citizens of Eureka are saved! The wildlife that depend on the lake and its surrounding ecosystem, however, will not be so lucky. But no one mentions them. Stark takes a second to criticize Carter's driving skills. They get out of the tunneller and watch the lava pour into the lake. They're, like, really close to that lava. I think their faces should have melted off by now.
Night falls on Eureka and a lava-created steam cloud rolls in. Carter and Hood are hanging out at Café Diem when Stark and Allison enter, fanning themselves. "That magma's gonna be venting for days," Stark says. "I think, technically, it's lava," Carter says. Ha! Hahahaha! And the expression on Stark's face is great, too. Allison says Carter and Stark should "team up" more often, revealing a heretofore unknown kinky side. Allison and Stark walk away, and Hood reveals to Carter that he's very happy in his post-geologist life. "Living with that kind of pressure isn't for me anymore," he says. Ugh. I was sort of hoping that we had worked through the theme shoehorning once the volcano erupted.
Stark returns, sans Allison, to quietly praise Carter. Then he runs away, allowing Fargo and his robot dog to enter the scene. Fargo's holding a big Best in Show trophy, while his dog pees on Carter's leg, thereby proving that the reason why he's so realistic is that he's a real dog. Fargo runs away before he can be arrested for cheating. Yes, he cheated, but I blame the dog show judges. Surely they should have figured out that Fargo's dog was real when they lifted him up and found that he weighed hundreds of pounds less than his robot opponents.
