There's a suction cup thingy that didn't get properly removed. Like when the nurse hooks up wires on Kirito's body, she uses those little suction cups.

I learned that Asuna's a way better main character than Sinon or Kirito. I mean, I guess it's mostly because her path to getting "stronger" (since this show's theme (other than "nice guys" in reality are rapists) seems to be something about being "strong" and how it has a fuck load of definitions according to a shitton of people or whatever) is a lot more grounded and easier to relate to. Yuuki was also not annoying which is a breath of fresh air in SAO.

Sinon's arc was just a bunch of lolwutz for me. I've never killed anyone so I don't know how it feels like, but it just felt super unrealistic that seeing a toy gun in real life triggers her while seeing a realistic gun in a game doesn't. I get that the reason is because death is fake in the game, but it's not like when she's in the game she can't remember what she did. And there's the nice guy rapist in her arc so it's completely ruined.

I mean overall the only part worth watching in SAO II is Mother's Rosario, but it's not like it's super great or anything.
