Bugs

 * Calvin enters an inaccessible area called Vault 81 Holding Cell shortly after he is spoken to.
 * On PC the only way to speak to him again is to open the command console by pressing the ~ key, type "153855.moveto player" without quotes, press enter, and finally press the ~ key again to close the command console. This teleports Calvin to the player character's location where he can be spoken to. Shortly after speaking to him (in Vault 81 at least) he will return to the holding cell. Alternatively, type "player.moveto 153855" again without the quotes, press enter and close the console, this will teleport the player character to Calvin's current location.
