" What’s he doing?” I asked, leaning over the side of the boat, searching for him beneath the water. If the tow rope had gotten tangled, he might need help. And someone would need to go in the water with him, perhaps accidentally sliding against him down where no one else could see.
“Boo!” A handful of bryozoa rushed up at me from the lake.
I screamed (for once I didn’t have to think about this girl-reaction) and fell backward into the boat. Sean hefted himself over the side with one arm, holding the bryozoan high in the other hand. It dripped green slime through his fingers. “Bwa-ha-ha!” He came after me.
I squealed again. It was so unbelievably fantastic that he was flirting with me, but bryozoa was involved. Was it worth it? No. I paused on the side of the boat, ready to jump back into the water myself. He might chase me around the lake with the bryozoa, but at least it would be diluted. On second thought, I didn’t particularly want to jump into the very waters the bryozoa had come from.
Sean solved the problem for me. He slipped behind me and showed me he was holding the ties of my bikini in his free hand. If I jumped, Sean would take possession of my bikini top.
I had thought about double knotting my bikini. I’d hoped against hope that Stage Two: Bikini would work, and that Sean might try something like this. Of course, I didn’t really want my top to come off in front of everyone. Nay, in front of anyone. But I’d checked the double knots in the mirror. They’d looked…well, double knotted, for protection, sort of like wearing a turtleneck to the prom. I’d re-tied the strings normally.
Now I wished I’d double knotted after all. Sean brought the dripping slime close to my shoulder. “Go ahead and jump,” he said, twisting my bikini ties in his finges.
“Sean,” came McGullicuddy’s voice in warning. This surprised me. My brother had never taken up for me before. Of course, none of the boys had ever crossed this particular line.
But that was nothing compared with my surprise when the bryozoa suddenly lobbed out of Sean’s hand, sailed through the air, and plopped into the lake. Adam, standing behind him, must have shoved his arm.
Which meant I owed Adam my gratitude for saving me. Except I didn’t want him to save me from Sean, and I thought I’d made that clear. Saving me from Sean with bryozoa…that was a more iffy proposition. I wasn’t sure whether I should give Adam the little dolphin look again when our eyes met. But it didn’t matter. When I turned around, he was already stepping over Cameron’s legs to return to the driver’s seat. "
