Loved it. I recall an interview where Hoshino stated Cross would appear in flashbacks with Nea's backstory, and be younger. So I was thinking we were gonna see that 1st while still not knowing his status. I definitely wasn't expecting to see him alive / active again so soon. Though, it has been 54 chapters before this revelation.
The chapters seemed like a good starting point for finding out some big information. An intro chapter basically that may lead into, or foreshadow, an upcoming arc.
I like Allen's resolve. he genuinely seems interested in helping others, and is probably the most selfless character in the manga. But it's nice he's trying to find more answers now and make more choices. In 167, he mentions not caring about the 14th and that he was walking for Mana. now, he seems more aware - he's not living just for Mana anymore. he's finding his own path, remembering promise he made to Lenalee, and now trying to find out what the deal is with Neah instead of blindly living for Mana. So seems he's looking at different sides now.
And loved Cross' speech to Allen where it was a bittersweet moment of him showing he cared, and openly admitting it (sorta) for once. Hoshi did great with his expressions, where he looked a mix or respectful of Allen's resolve, but possibly more hurt that Allen is determined to fight the inevitable (far as he knows) and suffer, rather than living peacefully and out of the war for a bit.
