I honestly don't know why I put that in a spoilers tag... but yeah. If the swearing is more often than occasional, then it'll become detrimental to both the character and the series as a whole.
I, personally, really enjoyed the issue. The writing is "mainstream" and "generic" (whichever term you're comfortable with), but I'm just happy it's not "classic writing" like Claremont's writing. Not to say that Claremont didn't do an amazing job back then, but he just had so much narration, thoughts, and dialogue, that it took me forever to finish one issue. I also never expected Humphries' writing to be as sophisticated as say... Hickman, which is why I'm not really disappointed because I didn't have high expectations.
I also loved the moments between Storm and Psylocke; how they talked about their relationships without, well... talking about them. Haha! I'm really looking forward to their friendship as Humphries has promised. I was talking to a friend, and mentioned that Callisto would be a great addition to the team. I don't know if she makes any sense, but I'd love the mirror: Callisto is to Storm as Spiral is to Psylocke. But yeah. Pretty random character. If anyone joined, I would have wanted it to be Rachel, but since she's in Wood's X-Men, I would have to say... I honestly don't know.
So far, this is one of the better Marvel NOW! books. It cuts straight to the point; it answers questions but still leaves enough suspense to pull us in; there's a perfect blend of comedy, action, drama, and seriousness; and the characters are being pulled into directions that are fresh and makes them interesting again. One of my fetishes (yes, the first word that came to mind to describe how I'm feeling) is when a writer humanizes a villain. I see this happening with Spiral. A lot of fans are saying, "Spiral doesn't feel like Spiral," but that's Humphries' whole point. Rather than being evil and insane, Spiral actually feels pathetic for once-- she didn't try fighting Betsy back, but she was trying to talk to her. That's definitely a "whoa" moment. It really makes me wonder what was able to do that to Spiral; and a story is supposed to make readers wonder and think and bring up discussions between one another. Definitely a plus for Humphries here. As for Fantomex and Cluster-- for all you Fantomex haters, just be glad that they are getting development that doesn't depend on Betsy. I'm not telling you to like him/them, but at least try to be open to the fact that they're there, and without being a hindrance to Betsy's character.
