The Beast Within - S1.E10

While out in the jungle, Malone is hit in the neck with a poisoned dart and dies. A shaman, Lento, heals him and Malone is brought back to life, but Lento has been driven mad. He is sentenced to die by his village, but Malone rescues him. Summerlee is kept captive and will die unless Malone, Roxton and Challenger can bring Lento back. Lento leads them a merry chase, having booby-trapped the jungle, but the men do eventually catch up to him , and he is killed. In the meantime, back at the treehouse, Veronica and Marguerite have had a huge fight, and wind up down an old well, with a hungry dinosaur waiting for them above and snakes, water and each other, in the hole!
