The sound of an explosion high up in the sky is a reassuring one, and the distance is what he hopes is a good sign. However, considering things, Angeal can't really go outside to do a proper check.

Rather, he's busy getting a shovel and smacking an ID back like it's a baseball.

Byleth might catch snippets of the trash talk as he makes it back to the barn door. "Better not mess up my barn, took a whole two days to clear this out-" And that wet thud would be an ID smacking up against one of the wood walls.

The other ID seems to be taking a more cautious approach, considering what Angeal is waving around, and might even try to make a break for it... which is awkward, considering Byleth is at the exit.
