Deemer tells Hastings that the cause of Jacobs death was his impatience to see if the latest batch of the nutrient would sustain humans. As a result, Jacob injected himself with the nutrient which resulted in runaway acromegaly, which killed him in four days. What Deemer does not reveal is that Jacobs also injected his research assistant, Paul Lund, with the same nutrient.After Hasting leaves, the deformed Lund appears, attacks Deemer and partially destroys the lab. During this rampage the lab catches fire and the glass front of the tarantulas cage is shattered.
