For now, his Slate would stay where it was, snugly tucked into a small inner pocket of his leather trench-coat. Didn't want to risk dropping -or worse, breaking- it, while he was hauling crates around to meet with the hooks Kanji was maneuvering. Once it seemed that the boxes were in the correct positions, Sephiroth would stride for a moment to Kanji and the terminal to see how it looked from those screens.

"That should do it, perhaps?" Before heading directly for the stairwell back into the reverse room to check it from that perspective. He'd have been fine climbing the hook-ropes, but the idea was to get them all into the next room without any trouble.

Once satisfied, with or without some minor adjustments, Sephiroth then pulls out his Slate and texts back to Kanji.

Looks about right in here.
