The climax of "RIP Calvin" involves four out of our five main protagonists dying and Hobbes rushing through ship to save them as Bring Me To Life plays in the background.
The MTM being destroyed in "Thunderstorm" much to Calvin's horror and grief.
The entire Darkest Hour scene doubles as this: Thunderstorm has taken over, everyone has been put in dungeons like caged animals, Thunderstorm taunting Frank and Jack about his success and the fact that the world is literally dying.
