* In the GoldenEnding of the ''1'', Rogan's fiance, [[DamselInDistress Sophie]], survives the attack by The Chariot. And if the existence of Lisa in the third game is any indication, [[EarnYourHappyEnding her survival is canon]].
* In the special addition for ''4'', after the end of each game there is a 'Partner Rating' to judge how well the two players cooperated with each other. If you managed to get a very high score, [[http://fc03.deviantart.net/fs70/f/2012/179/c/0/agent_g_x_kate_green_by_johnnytlad-d559o8h.jpg this]] will be the message that you get.
-->As long as there are couples like you in this world, there will always be hope for us all.
* In the special G ending of ''4'', [[spoiler:G is shown at the site where James sacrificed himself to destroy [[FinalBoss The World]]. G declares that he's going to "take this fight back to the source", before [[DueToTheDead telling the deceased agent that it's time for him to rest]].]]
