"Teen Titans" How Long Is Forever? (TV Episode ) - IMDb
Back to List of Episodes. After Starfire falls through a time portal with a villain named Warp, she has an adventure alone in the future, and now she must find her friends' future selves and get back to her own time. Starfire tries to initiate her tradition, but everybody is too hung up in their own issues to listen. The Titans reassure Starfire that this is merely typical roommate behavior, and they would always remain friends.
What do an antique clock, a time-traveling thief and an alternate future have in common? One word: Nightwing. Why they throw a kibosh at us the size of a freight train.
Starfire notices all her friends drifting apart and tries to call their attention to it. Then, in a fight with a time-travelling thief, Starfire gets sucked into the future, where her fear has come true. Cyborg is confined to Titans Tower due to his final battery giving out, and him having to remain plugged into the tower's power source at all times. Beast Boy has become afraid of everything, locking himself in a cage to keep passersby away.
