The thing about these two is that they have this great brother-sister vibe. They watch out for each other, they joke, they fight, they lean on each other when their friends are dying (listen, it's tough to be an X-Kid, what can I say), etc., and there's no romantic undertone. When Hellion hangs out with Mercurt, he's actually a nice guy. It halfway makes me want to ship the two of them.
The truth is that the connection between all of the Hellions (Mercury, Hellion, Tag, Rockslide, Dust and Wither--and X-23, even though she was never officially a Hellion) have with each other is something special. (Which is funny because it seemed like at the beginning of New X-Men that the guys we were supposed to identify with were the New Mutants, and the Hellions were supposed to be antagonists.)
Anyway, here are a few moments that showcase their friendship:
( Under the cut. )
When we last left off, Sooraya and Cessily were fighting Belasco like the fierce ladies they are. Illyana was excising Megan's soul, and Noriko, Julian, and O*N*E are trying to figure out a way to save everyone from Limbo. (Also, mods, I have more than seven pages from each of two issues here, but they each had thirty pages of content including Endangered Species, where Beast is running around doing SCIENCE! to save the mutant population. I can try to cut it back down if that does not count.)
They find Amanda Sefton, who was in a coma and on the verge of death. Noriko shocks her back. Amanda says that "Belasco is coming for the children," and that they need to find Nightcrawler, who has the Soulsword. But he's in SPACE. "They're dead, then. The X-Men...the students...they're all dead."
"Shut up and get dressed. You're taking us to Limbo."
