"She's waking up I think." A female voice says and I open my eyes groaning and clutching my throbbing head.

"How is this even possible." Robin asks and I look over to see the girl is Miss Martian.

I stay lying down and see I'm in some hospital room, "the hell did you take me?" I ask Robin pissed off.

"The heart monitor says you're dead." Robin says pointing to the heart monitor and I look at them with a sarcastic 'really?' Look.

"I'm having a hangover, I'm not dying." I roll my eyes and sit up taking out all the wires connected.

"Why does it say you're dead?" Miss Martian asks.

"Because it's broken? I don't know." I lie standing up and leaning against the wall leaving the room.

"You're under our custody, you can't leave this mountain." Robin says standing infront of me and I smile.

"That's cute, now get out of my way." I say pushing past him and I find a zeta tube and go to the digital pad but see its locked and look over at Robin who's blocking me from using it unamused and the team behind him.

"Who are you and why does the monitor say you're dead. Are you immortal?" Robin asks and I sigh.

"I wish I was immortal, that'd be pretty cool-"

"Answer the question." Superboy says getting fed up.

"If you really are that interested I'm half vampire, I'm not dead, your monitor just can't pick up my heartbeat." I say truthfully and they look at me not buying it.

"We aren't joking." Aqualad says.

I focus on Robin's neck and my fangs poke out, "E-Either am I." I say closing my eyes and looking away from Robin, "Robin let me go before I kill you, I can't fight the urge for long." I say using all my strength to block out his heartbeat.

"Stay here."
