Mel is a human living in Diamond City in 2287. One first meets Mel in Diamond City's jail cell after Bobbi No-Nose sends the Sole Survivor to bust him out for The Big Dig quest. When pressed about his crime, the Diamond City jailer will claim that Mel was caught trying to reprogram bartender Wellingham from the Colonial Taphouse to give him free beer, to which he states he would have done the same had he the know-how.
He is the owner and creator of both the Sonya and Sonya Mk.II, heavily customized eyebots.
Mel can be found as a random encounter later on. He can be spoken to but no matter what is said he is not happy and just keeps walking. Sonya Mk. II follows him.
Mel will be flirtatious toward a male Sole Survivor when the sarcastic dialogue options are chosen in conversation with him, and comments on his looks when talking with Bobbi. He does not flirt with a female Sole Survivor.
Mel may join the player character simply by stealing the cell key.
When activating a Port-A-Diner, Mel will say "Yeah, I wouldn't touch that pie. I don't trust anything that looks that perfectly preserved after 200 years."
