Bugs

 * Calvin enters an inaccessible area called Vault 81 Holding Cell shortly after he is spoken to.
 * To speak to him again on PC, open the command console by pressing the ~ key, type, press enter, and finally press the ~ key again to close the command console. This teleports Calvin to the player character's location. At midnight he will return to the holding cell. Alternatively, type press enter and close the console to teleport the player character to Calvin's current location.
 * To prevent Calvin or other NPC from returning to the holding cell; go into the wall at the top of the stairs facing the bathroom directly to the left of Alexis' and Holt's room (it's viewable on pipboy map as Vault 81 Holding Cell) using the tcl command, select the door to enter, then immediately turn clipping back on so it'll actually let you enter he room. Remove all NPC from the room by using the prid command and moveto player once back in the hallway. May need to move them a good distance away as the children in particular will immediately try and return to the holding cell room which they can access by entering the bathroom door, or use tai to toggle their AI briefly and they'll stay in place. Once room is cleared, go back to the holding cell's door, select it, then type lock 1. Move POV so the "Unlocked" message disappears, then look at door again, it should now say "Novice Lock". NPC will not be able to unlock this and will stay in the halls if they don't have an assigned room.
