I'm actually a little confused by your sentence. What's the timeline here? You start off present tense, then shift to past tense. So John had been looking for Cam, and had bumped into him, and now he's... looking for Cam again and there's the Ferris wheel? He's trying to orient himself so he can find Cam again?

How about: He looks around, and there’s the Ferris wheel, and right, he was looking for Cam, had bumped into him (previously)

Also, whoa! Are you writing about John and Cam as teenagers?? If you are, omigod, I may have to marry you and have your babies!
