Smiling Larry

Smiling Larry is a traveling merchant appearing in Fallout 4.

Background
Larry is one of several random encounters throughout the game. He can be recruited as a weapons vendor and sent to a player settlement. When asked about his story he says "People want something, Smilling Larry find it and bring it to them, all Commonwealth know me".

Appearances
Smiling Larry appears only in Fallout 4.

Bugs

 * It is possible to have Larry at your settlement, but it is very very hard, spot him, kill his mercenaries and brahmin, lure him to the nearest settlement with 30 settlers, then go sleep 24h to make him friendly, use "work for me" dialog option, and go fast travel away, then fast travel back and assign him to the weapons emporium.
 * If Larry disappears after being sent to a settlement, he may end up in the "Quick test cell" limbo which is a very small test room, with other random NPC such as Scribe, Ness, Mr. Gutsy, etc. Ness will be hostile and may possibly kill any non-essential NPC. If he disappears, use to find him and other NPC.
 * Some Level 4 Merchants won't travel to or stay at your settlement after being assigned there. Solution: after the merchant has been assigned, disable them and any other travelling companions they spawned with, such as accompanying mercenaries ("prid [ref id]", "disable"); fast travel away from the area they spawned in; then walk, don't fast travel, back to that exact same area and a different random encounter should occur, such as wild mongrels or synths; if so, re-enable the merchant ("prid [ref id]", "enable"); fast travel to your settlement; and finally, move the merchant to you ("prid [ref id]", "moveto player"). Now the merchant should stay put.
 * It is likely that Larry will never appear at a settlement once hired.
 * It is possible to assign him to tasks by using the console: target him with, enter and , then fast travel to a remote location and return, after that you will be able to command him using the workshop menu.
 * Another solution is to head to the settlement where he is wanted, type in the console to select Larry, then, , and finally.
