150. It is always handy having a Time Lord along. He explains how these distortion fields work and that there is inevitably a doorway which also powers it. He feels along the field until he finds the doorway, discovers the Coptic Jars and deftly diffuses one. This deactivates the energy barrier in your area; and the downed field is detected by Sutekh, who orders Marcus Scarman to investigate.
Back at the hunting lodge, Marcus discovers Laurence. Laurence tries to make his brother remember their childhood in order to revive his humanity. The conditioning proves too strong, and Marcus lays his hands on Laurence and melts his organs killing him quickly. By the time you and the Doctor find him dead, Marcus is long gone.
Now that you have the Gelignite, the Doctor has a plan, he dresses in the mummy wrapping taken from the killed robot mummy, and simply lumbers up to the rocket and places the Gelignite down to be shot by you (to detonate it) with Laurence’s rifle. However, as you are about to shoot, you see Marcus coming out. You consider him a good target of opportunity, but you only have 3 bullets with you. You can always shoot the Gelignite with the remaining bullets.
Q: Do you shoot Marcus? or do you shoot the Gelignite
A. You shoot the Gelignite – go to 160
B. Shoot Marcus. Go to 155
