In regards to my thoughts on this as an issue in a critical sense? I think this was a flawed issue in the sense that it didn't have the same sort of character crackling off it like the other issues in this arc did. Not the weakest of the whole run for me (that's actually one of the earlier issues), but it doesn't follow issue 9's particularly strong showing as well as I would've liked.
This chapter is more fascinated with things to come rather than what it is, and I think that makes it feel more sped up than it actually is. It makes for an interesting read because questions are being asked, and new mysteries are being put out before us, but the this is basically a wrap-up. This is unlike the issue 6 wrap-up that functioned very similar, but was structured to go for maximum character and emotion. It ended on a question, yes, but the emotional playoff was strong. This issue the character moments between and from Jon, Jor-El, Clark, and Lois salvage it greatly. My stand out moments being when Lois basically says they'll need to make up for lost time, the honest concern Jor-El had for his grandson, and the look of clear pride Clark has on his face when his son says he'll "suit up" again. I also enjoyed the general youthful exuberance Jon still retains.
Also Lois' "hey! Only a couple of weeks" almost made me glassy eyed.
I don't have much of an opinion on the scar. Maybe Peterson forgot to draw it as early as last issue? Maybe it's a side effect from Jor-El's teleportation rod? I don't really care. Seems more like an aesthetic choice than a story one.
Edit: I had a gripe about the suit deciding to transport them now right after Jon's story at first, but then I realized Clark touches the suit right when it activates, and he seems to understand what's going on. I'm guessing after Jon told him that Jor-El gave him the suit, and used it to transport him to Earth, he understood what to do. Cool.
