He was known to his Lamplighter friends as "Sticky Hands", though now that he is grown up, he calls himself Jack. If asked what "Sticky Hands" is for, he replies mysteriously "Use your imagination." He's a nonstop-talking, annoying, exuberantly self-centered 16-year-old who acts like he's about 13 (as he hasn't been around enough adult role-models).
Sticky states that his age is 18. Everybody else says it is 16. In 2277, he is forced to leave, as all children of Little Lamplight must eventually do once they reach the age of 16.
If the Lone Wanderer fires Sticky, or refuses to take him to Big Town, Sticky he will remain in the area you fired him in until the next time the Lone Wanderer enters that map cell, at which point he dies.
If you kill him while he is saying good bye in Lamplight Caverns, the other kids will comment that they thought he was annoying.
If the player refuses to escort Sticky when first meeting him by saying that they "want to visit Little Lamplight first", Sticky will stand on the other side of the gate indefinitely.
If the player offers to escort Sticky to Big Town and continues through Little Lamplight via the safer route to Vault 87, Sticky will be left outside the door next to the hacked computer terminal. He won't join you in the vault search for the G.E.C.K. but will be the first to show up at Raven Rock after you have lost all your companions; with the amusing effect of the exit door opening and Sticky showing up with one of his random comments like "Are we there yet?"
If Sticky is wearing his party hat when you initiate conversation, you will have the dialogue option "What's with the party hat?". Choosing this option will cause him to give you the hat, as he says he doesn't "want it anymore".
The entire time you escort him to Big Town, he will attempt to "entertain" you with insane stories and prattle. With a successful Speech attempt, you may get him to stop the annoying chatter.
If you take him to Big Town after completing the quest Big Trouble in Big Town with the "Small Guns" option (teaching the townsfolk to defend themselves), then he will eventually comment that Big Town seemed like a bad place to live, but the fact that you helped the townsfolk means it's getting better.
If you escort him to Big Town but haven't done "Big Trouble in Big Town" yet, the other residents will tell you that Red has been kidnapped by super mutants, but Sticky is not to be told because it will upset him.
Unlike other followers, Sticky will set off your mines, often as you are planting them, usually with the result of him being injured or killed.
If you lend Sticky any armor or equipment while escorting him to Big Town and you don't take it back before reaching the destination, the only way to retrieve the given items is to pickpocket or kill Sticky.
Sticky often recites juvenile and poorly thought-out stories to "pass the time".
He is the only human character in Little Lamplight that can be killed.
