Father Companion - Alternate Ending Option for Fallout 4 Mod

MOD

This mod adds a side quest to Fallout 4 that will allow you to obtain the character known as "Father" as a companion after the end of the game.

A speech check must also be passed as Dean is reluctant to use the serum given Father's unfavorable view of biological immortality and his shutting down the program that allowed Kellogg to live for over 100 years.

Any previous progress done with Volkert carries over so you may be able to just cure him on the spot or only require one item of the two.
