Tikki pauses, lifting the Kang to point directly at Ohara’s face. In a sense,
she realizes, Ohara’s right. She isn’t here. Now that she’s faced with the
inevitability of making another kill, she remembers something, a previous kill 
she made for Adama. The memory comes to her clearly. It’s been flitting around
for days somewhere just beneath the surface of her conscious mind. She was on 
the back stairway of a residence tower, the Ardmore complex. A door opened and a 
young male came onto the stairs, and she killed him because he might sound an 
alarm and prevent her from reaching her target. It seems impossible now. She 
killed a kid, an innocent kid. The realization hurts.
