Ok, in the game Gerry mentions he has an older daughter named Sarah and since his last name is Harding so is hers. So is she THE Sarah Harding from The Lost World? I mean, i would fit. Gerry mentions how shes a couples years older than Jess, probably in her 20's and in TLW she's in her 20's. I'm pretty sure that she is the Sarah Harding from TLW i just wanted a Telltale Confirmation for good measure
