Remy obviously knows about this and is just like "hello again my children, muahahaha" (jokingly, and not bothering to be loud enough to carry to the whole group)
Laura and TJ are both O.O !!! Laura has a better poker face, TJ's more likely to outright squeal with her tail waving around. She actually cares less about the dinosaurs than the jungle etc. Laura is interested but also occasionally giving skeptical looks to the people who most clearly knew.
