Why? Because she got stupid. Because she knew the man on the stairs would 
shoot. Because, in the moment she had to think about it, Tikki didn’t know if
this male, Raman, could survive yet another blast from a gun. Because the idea 
that she had encountered a male of her own kind filled her with such urgency 
that she simply could not help herself. How does she explain all that? Answer: 
she doesn’t. "You tried to kill me. Why?"
