Ah, my bad. Bloody orange goggles make it very difficult to differentiate between pilots. I'd been under the impression that Wedge found Han & Luke ever since I first saw ESB in the '80s. How embarassing.
Dialogue's confusing, too. Luke switches between addressing "Rogue 2" and "Rogue 3" between sentences, but he appears to be interacting with the same snowspeeder. Oh, well; just ignore my third suggestion above, then.
