In episode 197, Pluto and Saturn were the last two senshi to get their Star Seeds taken.
The four Outer senshi decided to go and challenge Galaxia themselves as to not endanger Sailor Moon... or whatever other reason they might have had. When Galaxia was about to take their Star Seeds, Uranus and Neptune decided to become her minions. Their Star Seeds were taken, and the infamous Galaxia bracelets appeared on their wrists.
Once Pluto and Saturn realized that their comrades were serious about getting their Star Seeds, they allowed them to be taken when Uranus and Neptune fired. Right after Pluto and Saturn's star seeds got taken, Moon and the Starlights ran in. We have a very sad departing as the two outer senshi fade away. =(
