Many hours had already passed since the particular group of devils entered the Inn and split. During this time, they did nothing suspicious. They merely roamed the grounds of the Inn, separately, as if exploring the wilderness during an adventure.
Oddly, though, that abruptly ended when one of them spotted Velma. The devil stayed in the distance and only watched, but the rest from his group seemed to stop their wandering, and converged towards him. Since he was following Velma, from a distance of course, when they would finally meet, the entire group would be near Velma.
As for what would happen afterwards, only the devils themselves knew.

Lex did not plan an elaborate reunion, nor was he intending on a long, drawn out play for revenge. As angry as he was, he knew his first priority was to get the battalion back to the Inn. It was exactly for this reason that he was willing to take a risk with the stronger missiles.
