1) The answer is yes.

2) Haha! Sort of, yeah. They don’t look like they could stability support anything.

3) Teamed-up? I’d like to see that. Maybe that shapeshifting queen would be willing, but you can’t team up with Discord; his ego’s too big. That was the whole reason why he lost. He just stood there and let Twilight and her friends strike him down because he knew they’d fail.

If they came back at the same time, they’d probably go after each other, and that would give us time to mobilize against them both. Given a little preparation time, Equestrian forces could easily take out an army of changlings. And Twilight’s little unit could handle Discord again.

If they could really work together, would Discord be more dangerous with an army of changlings at his side? Of course. But I just don’t see that happening.
