When Squints is standing outside the pool behind the fence after being kicked out, the scene shows Wendy, the lifeguard, wet from Squints's point of view from behind the fence. Then it shows Squints turn around, and Wendy is dry or it looks like she is or it's a different girl because her hair no longer looks wet and is blonder. When Squints turns back around, Wendy is back to being wet.
