If there's a particular aspect of the story that needs improvement though, I'd point you towards the latter half of the chapter. The opening paragraphs did a really good job of selling this idea of the confusion and loss-of-bearings that comes with amnesia. It's the detail (like Jake checking his phone or his GPS) that aids the verisimilitude. But I feel like the stride is lost with the final length of the tale.
You might want to flesh out Jake's thoughts on the scenario with a little more exposition. Like when Jake sees the MK impostor for the first time - I feel like that should be an 'oomph' moment. It should feel like a surprise to both Jake and the reader. It's the prose equivalent of a comic-book splash page. But the effect is glossed over or lost because we don't really delve into Jake's reaction. I think that a story like this - one told from a first-person perspective and dealing with a very character-based situation - needs go deeper into the protagonist's mind.
Y'know what's funny? I woke up this morning thinking the exact same thing. I never even described the diner! I think the problem is that I get caught up in my own story and forget about the details.
Thanks for the feedback! I don't think I'll edit this post, but I'll be mindful of consistency in the next chapter.
Thanks, everyone, for reading, too!!
