>>6084011>>6084015+1, sure. That's the weird guy who wanted to be Mark's "friend", right?
Allies are out of question, who cares about their dirty laundry. Same with the girl.
Banks' issues are so obvious there's no need to ask.
See, I think it'd be weird for mark to treat this dream encounter like a fun game of "find out someone's secret! :D", because the whole situation is just so alarming. If I'd get a dream like that, sure, I'd ask about people I know out of idle curiocity, but mark is always in so much danger, mundane and supernatural, that I think he'd just go for something work/case related.
I guess investigating is the way to go for Mark, even in his dreams.
