Light, being busy with talking and dealing with the mayor, didn't notice Pixel as he introduced himself as she walked by. So far things had been going fairly well, and the mayor was a good ways into his speech when a smokebomb erupted at the end of the hall. Light, expecting something bad to go down and being one of the closest people to the mayor, got into a defensive stance to guard him. As the smoke cleared two metas appeared from it, once levitating and apparently controlling the brass cutlery while the other had drawn a katana and had an eerie blue glow around his mask. 

"I figured something was going to happen, but I didn't think they'd have this amount of backbone." Light said, catching one of the knives another meta had not blocked with his ice walls and putting it in her pocket space. At least there were some other metas around to deal with the assassins, Light didn't fancy a 5 v 1 while she had to protect a fragile hostage. Either way, while the other 3 metas kept psycho girl and katana boy, Light escorted and protected the Mayor and anyone else nearby out of the building / into a safe room, depending on who it was, the security of the building attempting the same thing. 

Since the target of the two metas was the mayor, Light was sure she'd have to defend the mayor from something else before he reached the saferoom in his office, making sure to stick close to him until he was safe.
