Admittedly, most Morrison issues read like mystery novels requiring a lengthy commitment. Much like most of my relationships
It was odd that there were a couple divergent story-lines that were dropped in then they resumed the regular storyline. And that odd future LSH story did tie in if you continued reading (see issue #10) although that future Legion is still a mystery as time-travel to the future is supposed to be off-limits.
Unless the future team came back and planted themselves insides his brain before or during the Flashpoint effect (as in "Legion Lost") but the inevitable temporal-incursion headaches really prevent me from really wanting to analyze all that time/space gobblety-gook
