Whodunit? PART 2: Back for more!!

Really tired, so this'll be short;

"Awesome! Although now we need to team people up fairly. We can't just put close friend's together, or else they'll muck around, and have the chance of being killed..." mumbled Rena, pushing her way to the front of the group.
"True that, but we also need the stronger people to go with the weaker, to protect them..." added Thesecretvalley.
"Well, who wouldn't mind going searching for the killer, and exploring like we did last time?" Niall threw in. Most hands shot up staight away like Matt, Niall, Thesecretvalley, Ollie, Brad and Rena. Some hands were raised with hesitation, and others not at all.
"Well, if you don't want to come, you have to stay in a big group together, you understand me?" said Matt.
