Perkins (Mummy on the Orient Express)
From Tardis Wiki, the free Doctor Who reference
Perkins was the Chief Engineer on the space Orient Express. He worked with the Twelfth Doctor on the case of the Foretold, starting "the clock" whenever the Foretold attacked. After the threat was over, the Doctor subtly offered him a chance to travel with him, but Perkins declined. (TV: Mummy on the Orient Express)
