Well then, can we just assume the island is on the Matriarch? If we assume it enough, it's got to be true!
I can't actually. It's a very debilitating condition. I can't go around blind corners unless someone reassures me there are no dinosaurs around them.
"Actually, there is a dinosaur aboard the Matriarch." Oh, yeah! George the Pterodactyl! He was @Dreamer's pet, but got left behind when Dreamer quit coming around. You see that? That there is what you call 'continuity.'
