Personally, I'm enjoying the warmth and sincere shows of affection between Logan and Scott. Some people might baulk at the subtext, but I'm perfectly comfortable with it. Fuck it, they even seem to be hanging out when Jean isn't on the scene...
Although I'm straight myself, I find the new status quo to be refreshing. Whether you choose to read romantic intention into their interactions or not, the whole perpetually being at "loggerheads" because of their shared feelings for Jean dynamic is very much played out. They both have clearly moved past the "alpha-male bullshit" that characterised their earlier interactions, and have come to respect and admire each other. Prior to Schism, Logan was very much Scott's righthand man, his "go-to guy" when things were at their worst. Furthermore, Logan would run through a brick wall if Scott said it was necessary.
In my humble opinion, I think that it makes perfect sense that their absolute trust in the field would manifest into some form of closeness away from it. I hope we never revert back to the cliched love-rival bullshit. The Scott-Logan-Jean-Emma love rectangle has moved past monogamy and petty jealousy.
Long may it reign! Vive La Krakoan sexual revolution!
