Doctor and Benton pursue Brigadier into Gel's path

The Gel slithers through a reconfigured doorway into the lab as a living weapon representing Omega’s vengeful reach. Its translucent form pulses with scarlet halos, dissolving solid matter—including Benton’s rifle—on contact and driving the Doctor and Benton out of the lab into the hallway.

The Second Doctor treats the wooden recorder as a fragile tether to his identity and continuity, kneading its ivory-smooth grain while insisting on one more look amid the unfolding catastrophe. His physical delay turns the otherwise mundane device into a narrative hinge that briefly suspends safety protocols.

The UNIT antimatter research laboratory has warped under antimatter distortion, flickering interfaces confirming it is no longer their familiar facility but a fragment of Omega’s antimatter domain. When the Gel smashes through the altered doorway, the lab ceases to act as refuge and becomes an immediate death trap.

The extents of the transformed laboratory dissolve into a desolate extradimensional shore visible beyond the doorway the Gel uses. Although not physically entered here, the alien shoreline’s presence signals the rupture of normal spacetime and frames the corridors beyond as escape routes rather than safe paths.

UNIT’s authority frays as antimatter distortion warps their antimatter research lab into an extradimensional pocket under Omega’s control. The organization’s institutional symbols and chain of command remain nominally intact—Benton obeys orders and the Brigadier acts as official representative—though their ability to enforce safety collapses the moment the Gel breaches containment.
