Matt was having a difficult time understanding this woman. She was far too excited about two strangers dying. He was certain Freya was a stranger and had no connection to him, though, because they probably wanted two completely different people to test...whatever they were testing. Plus, he had never seen her in his life. He almost smirked. Considering her personality, that was probably a good thing. And the science woman had mentioned daggers. 

He wasn't sure what to do next, though. Freya was bent on getting answers and the science woman was bent on keeping them to herself. He decided against getting between the two of them. He was aware that they were wasting time, but without some information they would have nowhere to go or look. He took a step back and decided to give Freya a chance. The science woman hadn't answered the first few questions yet, so asking new ones would be pointless.
