I don't think there's any doubt Palm drew the short straw when the jobs were handed out for this mission.
Leol's "borrowed" ability is buy time - because he's sucked the oxygen out of the room with his massive lung capacity, and Leol is slowly dying of carbon dioxide poisoning. It's a brutal way to go, but while Morel doesn't seem especially sadistic he's not sentimental either, and he's got bigger fish to fry. Of all the Hunters we've seen in H x H, Morel would have to rank in the very top echelon in terms of pure formidability.
sexual slave to a despicable toad like Bizeff, but she has to force herself to go to the same place that broke the mind of a strong Hunter like Knov. It's hard to tell exactly what happens when she does, but it appears as if she recoils from Shaiapouf's aura, which suddenly disappears - and then is replaced by Neferpitou's, which is even more terrifying. Perhaps this simply means Pitou has finished repairing Meruem's arm and is free to resume his role of protecting the perimeter, but either way it seems as if Palm was paralyzed with her fear and may very well have been caught. Gon may soon have another big log to fuel the fire of his rage.
Killua wakes up after having been out for two days, convalescing in an underground hospital under Ikarugo's concerned eye (the aspiring squid is actually sitting by his bedside). Naturally the first thing Killua does when he wakes up is ask how long he's been out, and the second thing is announce that he's leaving. There's still the matter of his bill, though - 1.8 million Jenny, payable in body parts if cash is unavailable. This prompts a quick call to Gon, who's overjoyed to hear his friend's voice at last. Kill also gives everyone a quick but rather showy display of his ripped torso as he's changing into his own clothes - holy crap, those abs! If there's a BYOB party after Meruem is defeated Killua will be all set, because he's sporting a twelve-pack (one for each year of age?)...
Ikalgo is powerfully moved by this display (the character, not the physique) from Killua and sees in it a sort of idealized version of the world he always hoped he'd be a part of, a kind of Bro-paradise where guys watch out for each other and expect nothing in return but the same in kind. The essence of Gon and Killua's charismatic ability to draw in other strong people, it seems to me, is that they represent this unvarnished childlike ideal of loyalty yet have the ridiculous level of strength to back it up. And it's a good thing too, because allies like Ikalgo are Meleoron are even more vital with Knov, in Morel's words, "probably out of this fight" (which is what I speculated). And it appears that Meleoron and Knuckle have hit it off in a big way, just like I figured - these dudes are bros if I've ever seen 'em, and they were born to exchange fist-bumps with each other. It's a bromance that was meant to be. All this is a nice little burst of hopefulness, but the truth is that the real enemy hasn't even been confronted yet, and all that the good people - and Chimera - have been through already is nothing compared to what they still have to face. They're going to need every ounce of fraternity and loyalty they can get.
One final note this week: 2013 manga sales were reported a few days ago, and Hunter X Hunter finished in 8th place (ahead of ongoing giants like Bleach and Fairy Tail) among all manga in Japan, with 4,231,475 volumes sold. That’s despite the fact that Togashi has been on hiatus for almost two years, and there were no new volumes of H x H released during all of 2013. It’s a truly astonishing testament to just how popular this series remains, and just what a jugguenaut it would become if Togashi-sensei ever returned to drawing it.
