Troubled Water

S3, E10: With Crane's toxin poisoning Gotham's water supply, the city is in chaos. To make matters worse, Crane has pinned the blame on the Titans, turning the terrified citizens of Gotham against the team. To regain the city's trust, Dick convinces the Titans to turn themselves in to Barbara and the GCPD. But with Red Hood buying off an unstable police force ripe for corruption, nothing is going to go as planned. With the Titans in disarray, Gotham on its own, and Wayne Manor soon to become "Crane Manor ," things are looking particularly bleak. Except for the unexpected return of two Titans - Rachel Roth and Donna Troy.
