Elizabeth was just as nervous as Connor, probably even more so. It was a long while before she got any response to her tapping and she felt fear that he didn't understand her and was going to react to having no verbal response with his natural hunters' instinct. In the following silence, she was reminded that if anything went wrong between them she was probably going to get a silver bullet faster than she could blink. 

She would wind up with her soul going...where ever cursed vampire souls went...and he would just continue on his quest, killing the bad monsters. 

Part of her nervousness evaporated though, when he began to speak to her again, meaning that he could understand morse code- meaning she could communicate even while trapped in there. With a small smile of victory, she pressed her ear against the door and focussed on his footsteps. When they sounded far away and stopped, she slowly turned the knob and cracked the door. She wouldn't looked at him, but just quickly grab the bloodpacket and close the door back up. Seeing the red blood and feeling its warm in her hands was a comfort in a way. The comfort didn't last long because she sank her teeth into and through the plastic skin. Her thirst became strong again, and though she tried to drink slowly, she found that the packet didn't last very long and it became painfully clear to her that a pint was just enough to tease her thirst. She needed more, but both her options were the worst of the worst....drink cold blood after nice warm blood...or losing to her needs and getting killed. 

She grimaced over these options as she tore the packet open and licked the last of the blood that stubbornly refused to come out. After she was done, she dropped the packet onto the floor and looked at the door. She had to do something...she couldn't stay in there with the bit of his blood teasing her, and him on the other side with a gun waiting for her to inevitably give in to this strange torturous moment of fate..

Feeling the pressure, she again scoots to the door to try to communicate. 

Connor...am lost...need more but trapped...it is a bad situation.

Her eyes traveled to the door knob. It would be so easy to close the difference, she found herself thinking and her frustrations rose with the conclusion of those thoughts. She wanted his blood so bad...to viciously tear into him in a most satisfying manner...the images even played infront of her eyes...but she didn't want to hurt him...and she didn't want to give up.

im sorry.
