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.

On the, the Mechanic will attack nearby enemies by throwing her Wrench like a boomerang to defend herself.

Names
The Mechanic may have any of the following names:

Quotes
When Goblin Tinkerer is present: When Arms Dealer is present: When Tavernkeep is present: When found in Dungeon: When homeless: During Blood Moon: During a Party:
 * "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, watch where you're going! I was over there a little while ago!"
 * "Hey, [Name of Player], did you just come from [Name of Goblin Tinkerer]'s? Did he say anything about me by chance?"
 * "[Name of Arms Dealer] keeps talking about pressing my pressure plate. I told him it was for stepping on."
 * "[Name of Tavernkeep] offered me a Root Beer, I told him to give it to me in a square cup." (Reference to a math joke; mathematical squares and roots cancel each other out, therefore the result is simply beer.)
 * "Thanks! It was only a matter of time before I ended up like the rest of the skeletons down here."
 * "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!"
 * "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?!"
 * "Do you think anyone would mind if I wired a cake with bulbs instead of candles?"

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."
 * The Mechanic has a crush on the Goblin Tinkerer, as referenced by her quotes, and judging by some of the Goblin Tinkerer's quotes, he has a crush right back.
 * Apparently, the Clothier/Old Man 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.
 * Rarely, the Nurse and Mechanic can both have the same name, either Kayla or Amy. This can cause the Merchant to say on a Blood Moon, "Oh, great. I can hear Kayla/Amy and Kayla/Amy arguing from here."
 * The line, "[name of Arms Dealer] keeps talking about pressing my pressure plate. I told him it was for stepping on," is a vague sexual reference. The Arms Dealer is apparently hitting on the Mechanic, using innuendo, but she doesn't get the euphemism and takes his comment literally.
 * This might be the reason of the conflict between the Nurse and the Mechanic, since the Nurse has a crush on the arms dealer.
 * During a party, when the Mechanic dons a party hat, her hairstyle is different. She wears it down instead of up in a bun: Mechanic (Party).png. This makes sense as wearing a party hat while having hair in a bun would be cumbersome.
 * Her ability to throw her wrench like a boomerang to defend herself may be a reference to Ratchet from the Ratchet & Clank games, who can do the same move.
 * Some of her names, "Autumn", "Dawn" and "Ginger" are references to the color orange and thus to her red hair.
