I'm really interested in that story you mention about Sarek Amanda, I'm not really a huge fan fiction, but I'd really be curious about reading that, especially if you say it's good.Discovery 'Prime' Sarek, someone that important we would be found in no time. Plus Vulcans know how to survive in strange places
(there is a fanfiction.net story on Sarek and Amanda ,meeting this way, and no it ain't my story but its a good one )
I was going to say Mr Data, but thinking about it more I might take Wesley Crusher. He's brilliant at figuring things out and thinking in ways no one else would, and he's especially resourceful, like how he was in "Final Mission". He's also cute and non-threatening. I feel Data would totally be a close second.
