This is possibly the reason for her frequent travel. Terra returned to the Titans and joined the team - but was secretly working with Slade to destroy the Titans from within. Never truly losing faith in Terra, Beast Boy stepped in between her and Slade and finally made her realize the error of her ways. Later that night, Terra sends a mysterious email in her room, and is startled by the sound of a knock on her door. Terra appears in Issue 51, which is set after the series finale of the animated series. After Terra ran off, Robin knew she was heading to Slade.
