Reasonable, but not convincing, but still worth a read, Anon. I went 19th letter and went with Stevens as @snowden is the normal reference. Similarly, for 3 as 'C' as Clinton, the link being Benghazi, but I'm not buying my own initial thoughts. There was a Q post referencing 19 hostages before, but I'll be damned if I can find it. Something along the lines of lives protected, thought it was late December but need to really hunt for it. The Barlow take to me references the sell out by Snowden of honest whistleblowers, but some anon posted a link to a story referencing the individuals you listed, but it didn't seem mainstream enough for a reasonable explanation. Agree on the sub being subcontractor rather than submarine, but that is still plausible.
I'd been bitching about Q-Team being a bit weak on substance and on clues since the drop before this was 'The Public will know soon' or something like that, I was prepared to wait, but when this one hit it seemed Q-Team was still intact. Later, that other longer post his q-team board and things seemed good again. Throw in the McCabe firing and 3 booms this week and a lot of hope & faith restored.
We'll see, hopefully some clues will be given on this Q post you took a stab at. It's better to let OPs play out before showing your hand, but it does seem Snowden has fleas from the CIA dogs he's been lying down with.
