At first, Jace's words just slid over Caitriona, the name and the occupation absorbed, but nothing else. She listened as he listed his history a bit, but didn't bother to store the information under important files in her mind. After all, it was probably something that would never come up again - or at least, not on business anyway. And she didn't really think that this guy was up for making any small talk that didn't have to relate to a mission, so there was no point in storing the data.
Basic first aid... It definitely wasn't one of Caitriona's strong suits. She was a gunman - gunwoman, which meant that she rarely got very close to her target and even more rarely got injured. The times that she had... medics had always been available and willing to help. It was their job, after all.
She watched as he nodded to Ghost in deference, before he continued with a statement that was anything but. It made her smile absently, and she glanced at Ghost to see his reaction. Before she could register it though, Jace turned to look at her, nodding his head slightly. His lips spread in something that might have been classified as a grimace on someone else's face, but on his? Caitriona wasn't quite sure, but she had a feeling that the medic was giving her a smile, a cold one, yes, but still, a smile.
"While God may not have a hand in things, I certainly will do my best."
Her eyebrows rose, arching into fine bows, as she stared at him. From the look on his face and the tone in his voice, it was meant to be a quip on her. As if he knew her beliefs. She locked eyes with him for a moment and then blinked, relaxing herself and lowering her eyes.
Not everyone believed in God - she knew that very well. However, she also knew that God did exist. He might not interfere with life very often, but He cared about His creations and watched over them all the time - always and everything. God would protect her, and after death, He would welcome her into His kingdom. Those who didn't believe lived cold lives, sad lives - lives with no meaning in them. They didn't understand that every life was made by God and that every life is lived for Him. And unfortunately, it was their loss, not God's.
Still, even knowing that, Caitriona felt a bit of a pique under her skin. She felt challenged. Lifting her head, she smiled at Jace, keeping the smile light. "I think I'll take you up on that offer. I'd like some basic first aid training." Her eyes flickered to Fiona and Zachary. "If Fiona and Zachary don't mind, we could go watch their fight, and then afterwards, you could show me how best to take care of minor injuries." She looked at Fiona and Zachary. "Do you guys mind?" And then at Ghost, "Ghost, sir? Do you have anything for us to do?"
