Yeah, there are. They're anime-art more than the manga-art, so they look dorky, of course... well, the ones on the box do.
Most of the "progress" is Allen holding her hand and getting a little jealous. ^^;; There hasn't been any real development since the Jasdevi battle (unless you count Allen giving death threats to Tiki). Hopefully, this will increase, now - Komui will be around, after all, and the two are good friends, so...
Nah, with Komui's sister complex? I doubt that their relationship will flourish at HQ, in the field maybe but not at HQ. Maybe if they went about it sneaky like, maybe then.
Oh, I meant there will be more of a focus on a relationship with Komui around. xD He's so paranoid and all - if he saw them holding hands, even once? And maybe the challenge of having to hide anything, or not being able to be close, will make someone think about it. ^_^
...or maybe Lenalee will randomly start making out with Allen in the middle of everything just because she's happy to be back, and, well...
Well.... Maybe the reason he saved Tykki was because Allen really wanted to save both human and the akuma.... And since Allen thought that Tykki's Noah power has gone he wanted to make Tykki to be a normal human....

Of course, doing such a thing would be illegal probably back then, let alone today, since Tiki is a murderer and should at least be handed over to the authorities or whoever...
