Didn't know she was a vimpire

When they were trapped, Tupac just silently prayed for safety of his love. He hoped that they will more interested in his interrogation, but not in their.

But their capturers were more intelligent, and that's why they used his love against him, torturing her, and making him watch. But last drop was when they killed her in his eyes, and Left-Eye just can't hold back desperate scream.

He watched them to pull her in the corner, like it somehow helps him to hide a body.
So when she moved he doesn't even react, thinking that this is hallucinations.
