Mechanic

The Mechanic is an NPC who sells various Mechanisms, as well as Wire Cutters and Wrenches, allowing the player to build wired devices like Traps and critter engines.

The Mechanic must be saved from the Dungeon after killing Skeletron. She will randomly spawn near the player while they're exploring. Talking to her in this state will free her, and she will wander the area until she gets killed or until the player moves far enough from her. After that, she will move into an available house like any normal NPC. If the Mechanic is killed, she will respawn if there is a house for her, rather than needing to be saved again (the same with the Stylist, Goblin Tinkerer, and Wizard). A Lifeform Analyzer can detect her while trapped in the Dungeon, showing "Bound Mechanic" when she is nearby.

When enemies are in her vicinity, the Mechanic throws her wrench at them, as if it were a boomerang.

Names
The Mechanic may have any of the following names:

Quotes
During Blood Moon: When homeless: When found in Dungeon:
 * "Always buy more wire than you need!"
 * "Did you make sure your device was plugged in?" (Possibly a reference to "The IT Crowd", or a general statement made by many people in IT about "malfunctioning" devices.)
 * "Oh, you know what this house needs? More blinking lights."
 * "Hey, [Name of Player], did you just come from [Name of Goblin Tinkerer]'s? Did he say anything about me by chance?" (Only if Goblin Tinkerer is present)
 * "Hey, watch where you're going! I was over there a little while ago!"
 * "[Name of Arms Dealer] keeps talking about pressing my pressure plate. I told him it was for stepping on." (Only if Arms Dealer is present)
 * "Oh, let me guess. Forgot to buy enough wire. Idiot."
 * "Just-could you just...Please? Ok? Ok. Ugh." (Possibly a reference to "How I Met Your Mother")
 * "I don't appreciate the way you're looking at me. I am WORKING right now."
 * "All I want is for the switch to make the... What?!"
 * "DON'T MOVE. I DROPPED MY CONTACT." (A pun on "contact", a device that an electrical current passes through, and "contact lens")
 * "But I was almost done putting blinking lights up here!"
 * "Hold on, I've almost got wifi going down here."
 * "Hey, watch where you're going! I was over there a little while ago!"
 * "Thanks! It was only a matter of time before I ended up like the rest of the skeletons down here."

Trivia

 * There appears to be conflict between the Mechanic and Nurse during a Blood Moon. When both are present, they have various hostile sayings that replace their standard quotes. During this time, the Merchant has a chance of saying, "Oh, great. I can hear [name of Mechanic] and [name of Nurse] arguing from here." These, along with her Blood Moon quotes, could be PMS jokes.
 * The Mechanic has a crush on the Goblin Tinkerer, as referenced by her quotes, and, also referenced by some of the Goblin Tinkerer's quotes, he has a crush right back.
 * Apparently, the Clothier was the one who tied up and left the Mechanic in the Dungeon, but he only vaguely remembers, as revealed in one of his quotes when the Mechanic is not present. Surprisingly, the Mechanic herself never mentions the Clothier doing anything to her.
