Things to Come!

Things to Come! is a challenge

Challenge requirements
The player character must hear five references as to what the future may hold.

Triggers
The following is a complete list of triggers for the challenge. Note that there are only four triggers altogether - two during the dialogues with Christine and Father Elijah, and another two in the DLC's endings slides if the "best" endings are achieved for Christine and Dog and God.
 * At the end of Last Luxuries, in the Executive Suites where one finds Christine, ask her about "How long have you been hunting him?", and hear the entire topic which ends by asking her "Sympathized? Why?".
 * At the end of Heist of the Centuries, on the Vault Security Intercom inside the Sierra Madre vault, ask Elijah about "Where did you get the collars?", and hear the entire topic which ends by asking him "I've never heard of the place you're talking about.".
 * During the ending slide for Dog, if Dog and God are merged.
 * During the ending slide for Christine, if she lives.

Effects
Grants 75 XP upon completion.

Bugs

 * Due to the fact that the challenge completion threshold is set to five, yet only four triggers are present in the game, this challenge is essentially unattainable without exploiting vanilla bugs, or installing bugfixes that reduce the threshold to four.
 * When playing through and hearing the triggers nothing will happen, the challenge won't even appear in the Pip-Boy.
 * When Christine's slide is playing, all triggers may apparently happen immediately, causing the challenge to complete.
 * When Dog's slide is playing, all triggers may apparently happen immediately, causing the challenge to complete.
