Object
Wheel Station's Protective Force Field
The Wheel Station's protective force field encircles the entire station as an energy barrier, blocking Cybermen positioned outside from direct entry. Flannigan passes through it to return from external missions, prompting the Doctor to order Ryan detain and inspect him for a neck metal plate signaling Cyberman control. Cybermen fail to breach it initially, then direct Flannigan to sabotage it once Jamie and Zoe finish their spacewalk. They also lure the Doctor toward it, exploiting his urge to aid the crew by drawing him beyond its safety.
