Master's TCE Weapon

The TCE weapon is snatched from Peri by the Doctor, who immediately hands it to her with orders to redirect the villagers.

Before: In the Doctor’s possession, having been wrenched from the Master’s grip earlier in the episode or scene sequence.

After: Taken by Peri, who uses its symbolic power to enforce her command over the villains, though its full potential is not activated here.
