At least Inigo doesn't mind helping out with these things at all. If anything, if Soldat has questions, he'd rather have them come to him with said questions rather than keep them to himself and be uncertain about it.

"One time it was cut short. We ended up only being in that world for a few hours until this sudden.." His voice trails off, but this time it's just since Inigo is entirely unsure of how to even describe it. "It was like a big cloud.. a mass of black shadows started approaching us. The train pulled us all back onto it before we could do anything."

He shakes his head. "It hasn't happened again since, but I figured it's good to know, just in case it may appear again. The train seems really afraid of it."
