Decade 26 and 27, Black RX and Black world.
Or as I like to call it "Awesome moment 2."
Dual henshin aside, there really wasn't much to it. Tsukasa was being pointlessly nihilistic in it (Uncharacteristically so), Natsumi's only goal nowadays seem to be to start babying around when someone calls Decade a destroyer, and Kaito continues to take up all of Yuusuke's screen time.
Cameo was nice, though.
