Slash seemed extremely pissed with Edge after Reaper did all of the heavy lifting in destroying every one of the Stonehenge railguns. The fact that they're flying highly-advanced Tokyo fighter jets (four of them, no less!) doesn't help much either. And neither does the fact that their names are colored white in subtitles, something never seen before in Ace Combat. (Neutrals were always shown in yellow, friends in blue.)

Something about them seems off. Single Line is very mysterious indeed.
