Recap: Primeval S 1 E 2

Connor's big mouth gets him kicked off the team, just as a new anomaly appears in the London Underground. A nest of spiders and a huge centipede have infested the tunnels. When Stephen gets bitten, the team have to go after the culprit to get a sample of its venom to find an antidote. Things get even stranger when Stephen starts raving about seeing Helen, Cutter's long lost wife. She says she can give them the truth, but only if Cutter is willing to follow her into the past.
