Primeval: Season Two, Episode Seven

So quick recap. Leek has been working with Helen Cutter to collect various dangerous extinct and/or not yet evolved animals for some reason. He's already tried to kill Lester; Lester applied a Mammoth to the situation. Now he's captured the team and is showing off his ill-gotten gains. Oh, and Stephen, who's sort of vaguely a bit on Helen's side, has been fired from the team and has no idea at all about what's going on.
