Any analysis on the sub they had?

Looks like a smaller one (obviously not one of the nuclear kind ) ;)...

I thought it looked similar to the NR-1, which is actually nuclear:

i highly doubt its nuclear.
If for nothing else, for the fact that now that locke blew it up that would have left massive contamination problems for our losties... and i dont think the show will worry about that, not what they are looking for.

It looked like a prop to me.........for Juliet 's benefit. However I can understand why you'd drug her. You could go bonkers if you didn't like enclosed spaces.:biggrin:

I can also see drugging her so she doesn't figure out the location of the island, or any neighboring "ports" near the island.

Sub seems just a prop. Juliette truly thought she arrived that way, and that's why she was genuinely upset when it got blown up.

The sub a prop? Then how did they really get to the island? Why do that just to fool Juliet?
