In the base of the Teen Titans, right during the evening, all of the Titans were doing some usual stuff.

Cyborg and Beastboy were in the kitchen, eating most of the stuff that they could take from the fridge.

Raven was sitting in her room, reading some book while looking bored and sighing to herself.

Starfire was playing with her beloved pet, Silkie, as she was on the couch.

And Robin.. he was exercising in the living room, as he either tried showing off to Starfire, or just actually train his muscles.

BUT SUDDENLYYYYYYY-

Someone.. (which is YOU.) was under the building, as Robin could sense something around the base.. which was almost impossible to reach to.
