If you use eyebombs as indicators of "Deathloks," there's actually been several in the series, and probably many more by extension. Akela, "The Englishman," there was one other Deathlok/Centipede who got eyebombed in a midseason episode....As someone else pointed out above, the file room at Cybertek seemed to be full of records on *bunches* of Deathloks. And that seemed to be what Quinn was peddling to the US gubmint at the end of last night's show.
Um, because flashbacks can be, and usually are, in 3rd person instead of 1st person....?
If the flashback had been personal and specific to Ward, they would've used something like a V.O. to show that. Showing Garrett kill the dog showed how much of a *****e he really is. Plus, it makes no sense for the flashback to be about Ward having an attack of conscience when asked to shoot his dog, then flash forward to him *not* having an attack of conscience when asked to shoot his teammates.
Ward let FitzSimmons live. If he had followed Garrett's orders to the letter, he would've just capped them with the pistol, like he originally intended. Instead, he admits to FitzSimmons that he still has that "weakness" (i.e., a conscience), and drops them into the ocean. Yeah, they could still die, but he also is well aware that they're both resourceful enough to survive. So he's giving them a chance, even if it's a slim one.
Also, final point about "who shot the dog": Ward doesn't have the rifle in that scene; he has a pistol. Garrett has the .50 cal. End of story.
I didn't catch it, but I think you're right. Good eye. We might have our first "tie-in" to the Ant-Man movie.
