I'm tempted to tell you to put him where everyone else is since his short teleportation should not be able to bring him to Eos. But I like the prospect of him being killed by Eos more so I won't say that.
His portals, however, should be unable to catch any of the lasers. As KoL said, they fell vertically and there is no way he should be able to manipulate them as fluently as he did. Meaning all those Machina Eos destroyed stay destroyed.
@KoL
There is no longer light and Eos' window is now kinda scratched, we good?
Edit: And Lucille never even asked Artoria to go fight, so I guess she'll stay home.
