3. What is the name of the robot that Susannah and the ka-tet meet in Fedic?
From Quiz "Dark Tower VII - The Dark Tower"
Answer:
Nigel
In the beginning of this final installment, Pere Callahan, Jake, and Oy enter the Dixie Pig in 1999 New York City to find the evils that were awaiting Susanna-Mio's arrival. Although they have the power of the Sköldpadda (Can-Tah to "Desperation" readers), Callahan is unable to fight off the vampires that he once destroyed and he kills himself with Jake's Ruger as he and Oy escape through the kitchen.
Meanwhile, Susannah and Mia have given birth to the son of Roland and the Crimson King, Mordred, and he kills Mia in order to grow. Susannah takes the opportunity to fight back and she kills everybody in the room (including Sayre). When she shoots at Mordred, she accidentally misses and clips off a single leg of the spider-like creature. She also shoots out Nigel the robot's eyes fearing that he may be siding with the vampires and low men, but it turns out he wasn't. Regardless, Nigel carries Mia to the final door linking Fedic to 1999 New York where she waits for the remaining members of the ka-tet.
