Alright, time to go through the mammoth task of documenting this thing.

[S] Past Karkat: Wake Up is a video game-esque flash segment in Act 5: Act 2 starring the Trolls in their Ectobiology Lab in the Veil, soon after their first contact with the Kids. Karkat, Terezi, and Vriska are playable.

The flash allows the player to search through the lab, examining objects of interest and collecting items from treasure chests.
