Journey to the Sacred City - S1.E30

The DATS arrive at the Holy Capital, but once inside are quickly captured and placed in an arena for execution. There, they meet once again with an old acquaintance who they thought missing. Thankfully, the moment that Marcus displays his DNA, the Digimon set them free, as they realize Marcus is Spencer Damon's son who all remember him for his heroic deeds to them. Unfortunately, celebrations are short-lived when a squad of Gizumon comes to raid the city, but catastrophe is prevented thanks to the timely arrival of Keenan and Falcomon who return with allies.
