This woman seemed to be a veritable ray of sunshine on a cloudy day. Note the sarcasm. Killian questioned whether or not he should have just let her get taken by the creature, that maybe she would have preferred it that way. Then again even he wasn't in his top form with the virus going around so he couldn't try and decipher a person's life desires by the way they acted in the face of the adversities at hand.
She came without a partner? The plot did somewhat thicken but he tried not to think about it that way. To give her the benefit of the doubt. Truth be told he felt some pull to keep her alive because she was a woman. It wasn't that he looked down on women or felt they needed protecting, he'd been bested by women before, it was just that he was sure that someone out there loved her and he wanted to save some poor fool the pain of losing her. It was an unlikely kindness to a hypothetical stranger of his mind's creation. Nothing more.
"In that case we may as well travel together. I'm without a partner myself and it does appear you could use a second set of eyes. I'm quite confident mine could do the job." and he winked. That charming devilish wink. It just came like second nature. "So tell me. What are you doing out here other than attracting trouble?"
