Since the link isn't there anymore, but still open in my browser, however that works...

It shows two women in a fire lit cave, wearing antique robes, a younger, pregnant, injured one and a middle aged lady who puts herbs on the younger ones's leg wound.

The younger one: "Where are the rest of your people?"
"There's only me"
"How did you get here?"
"The same way you got here, by accident."
"How long have you...?
"Every question I answer will simply lead to another question, you should rest, just be grateful you're alive."
"There were other people on my ship, I need to..."
"No, if there are other people on the island, I will find them."

So I am sure we'll see MIB's and Jacob's first steps, or their predecessors, maybe even the beginning of the conflict. Exciting!
