Such Sweet Sorrow

Synopsis
Gallantmon digivolves into Crimson Mode and battles the Jeri Type Agent of the D-Reaper. After a fierce battle Gallantmon Crimson Mode finally destroys the Jeri Type Agent by punching his fist through it. Jeri Katou finally awakens from her long depression, realizing the meaning of destiny that she had sought since first meeting Leomon. Meanwhile, MegaGargomon is out of ammo, while Sakuyamon energizes Justimon with the remains of her fighting energy in a failed bid to destroy the Reaper. The Reaper is finally dragged back to the Digital World by the Digimon Sovereign.

It is revealed that Janyu Wong has uploaded the Juggernaut program into Terriermon as part of Operation: Doodlebug; later, MegaGargomon activates the Juggernaut in the D-Reaper's vortex, which is located in the link between the two worlds. This causes the flow of the vortex to reverse direction (reversing the D-Reaper's evolution), but the protective effects of the red cards soon wear off, and the Biomerged Digimon are devolved into their respective composites, putting them in danger from the paralyzing effects of the D-Reaper. The combination of the fact that they are in a quantuam bubble and the reverse flow of the vortex creates a reverse time effect that devolves the D-Reaper back to its original harmless form as it's sucked into the vortex. Also, Jeri and Calumon (who survived because Calumon somehow protected them with a forcefield) are saved by Takato and Guilmon who reach her by Guilmon flinging Takato to the two with his tail after they degenerate. Fortunately, they are then saved by MarineAngemon as the chaos of the D-Reaper disappears into the hole.

During the end course of the battle, however, Janyu realizes that the Juggernaut program, in being a vital instrument of the defeat of the D-Reaper, would also create the same effect that was originally intended by Mitsuo Yamaki earlier in the series: it would force all the Digimon back into the Digital World. If they do not return, they will disappear completely as the D-Reaper did. After the battle, as the phenomenon occurs to the horror and sadness of all the tamers and their associates (with the de-digivolving of the Digimon into their training forms, save Calumon and MarineAngemon). Janyu reveals to his son Henry that he knew after examining Terriermon that this side effect would occur and expresses his guilt, As the Digimon leave, Janyu attempts to comfort Henry by telling him the pain of loosing their friends will ease with time though Henry, crying, just silently shakes his head no causing Janyu to weep and fall on the floor.

Months later, Takato confides that life in Shinjuku has returned to a state seemingly like the times prior to the arrival of the Digimon and his first moments with Guilmon. He states that the lives of all the tamers as well as their family and friends have returned to normal, with school and life continuing as if all their amazing adventures had never happened. However, the tamers continue to remember their Digimon, for they promised they would always be friends when the Digimon returned to their world. Takato though, says he still visits the old places their group of Tamers spent time in hopes of finding Guilmon and to remember his friend. While strolling by the abandoned rest area in the local park where Guilmon made his home during his time in the Human World, Takato decides to look into the hole that Guilmon dug when he first found an entry point into the Digital World. He is shocked to see that the gate to the Digital World has reappeared.
