For sure, Time Travel seems to the reason, just don't know how/who does it. Though I can see Scott shrinking all the Avengers and them taking a picnic tour in the quantum realm as a possibility.
We still don't know how Scott escapes, last we see in AM&W he's stuck; then he's out in the trailer for IW:End Game
