Everything was going so damn well that Andrew couldn't even fathom that something bad could happen. It was an event hosted by the Beckett's after all, and he knew that they cared about him deeply.
Maybe it was just an assumption on his part, but he was fairly certain that they had already looked into who his father was, and had cut ties as much as they could with him and his family. Andrew was pretty sure that was what they had done, so after Mr. Dalton had been pulled away by some colleagues who wanted to talk to him, Andrew was with Maxwell, Richard, Rose and Jordan.
He didn't have his guard up, he didn't even think that anything could ever happen. He was practically defenseless to it.
