Chapter 9 Spoilers
Chapter 16 Spoilers
Maybe I'm just reading it differently, but the stutter, shy look, and illogical plan* don't remind me at all of the Bayonetta that watched out for Cereza and Luka. Bayonetta running blindly for Loki (note Balder's "What is my daughter doing!?" face) doesn't make me think of how Bayonetta slyly handled Cereza being kidnapped by Joy. It reminds me of a pre-teen girl trying to hang out with her crush without revealing she wants to. It's not the Bayonetta I'm used to at all.
Maybe I should just say it full-out: between the kiss and the scene after it, the exchange in front of the Gates of Hell, and the scenes before and after the last boss, I definitely thought the game was pushing a Bayonetta-Loki romance. Ignoring the age gap (this is a universe with ubiquitous time travel, after all!), this isn't necessarily a bad thing except for the fact that Loki is generally a dick who, besides one unexplained kiss, seems perfectly content with splitting ways with his partner. Between the ending and the Gates of Hell scene, Bayonetta seems to be the one pursuing Loki, not the other way around.
And that's just not Bayonetta's style.
I like how the Bayonetta/Luka semi-romantic-friendship was handled in the first game, but this just felt completely out of place (accentuated by other things I mentioned in my long post, like the un-triumphant post-boss cutscenes).
More power to you if you don't see the game this way. I watched all of the cutscenes from Bayonetta 1 numerous times, but I couldn't help but skip many of Bayonetta 2's after my first time through.
* She's justified a moment later by the Lumen Sage's convenient appearance, but Loki's point still stands that Bayonetta hasn't given a proper argument for why he should be dragged to Inferno.
EDIT: Was talking with a friend about this in real life and we hypothesized Bayonetta's unnatural attraction to Loki might be a "clever" reference to the Sovereign power to "control the eyes". Bayonetta 1 had plenty of clever early links to its later reveals, so perhaps they were trying to do the same thing here. I might take this as my canon explanation...
