Fireheart is a stupid sadsack idiot in this chapter. His sister is stereotypical and unimportant.

What, I can't just end this post here? Why not? Nothing substantial happens in this Godforsaken waste of a couple pages.
...Okay, if you insist, but you're gunna be just as bored and angry as I am.
We start the chapter with Fireheart moping around and experiencing more pangs as he stares at cats doing their daily duties. He internally monologs about how he misses his sister that he didn't even recall well enough to scent immediately, wonders if his mother was as loving to him as Brindleface is to her kits (which he should definitely remember), and angsts about his bloodlines.


What are you whining about, dude?! You helped dismantle a tyrant, cleared a popular cat's name of wrongdoings, saved an entire Clan, rescued and reunited with one of your best friends, avenged your "love's" death, became a warrior, got an apprentice, discovered the truth about a vicious murder, earned the respect of 99% of your Clan and earned the favor of a leader, all within, like, 2 weeks maximum. You're baller. Everyone recognizes it. Your blood has ceased to be important to anyone but shallow, one-dimensional attempts at an opposition against you, which hasn't stopped you at all! What on earth do you possibly have to pettily cry about now?!

Okay, so firstly, Fireheart just decides on a whim to go visit his sister, in kittypet territory, right after moping about being a kittypet, without considering that if someone (TIGERCLAW FOR EXAMPLE) catches him, he's going to be on high alert, THEN he dumps his apprentice that he got LITERALLY TWO DAYS AGO onto his friend who just got HIS apprentice two days ago, gives the flimsiest and stupidest excuse imaginable and runs off, and Greystripe just BUYS INTO IT?!
I just...I don't understand. I know Greystripe is an idiot, but the fact that he doesn't even question why Fireheart can't just bring his apprentice along is ridiculous. And, besides, they're best friends. He should be able to catch that Fireheart's up to something and at least ask for clarification. This is absurd.
Okay, whatever. Let's just keep going.
Fireheart makes it to his sister's house without any trouble, and this happens:

Aside from the fact that he should have been able to remember her name if he spent all night and morning thinking about her, is her name seriously Princess? That's the most stereotypical pampered kitty name ever, right next to Mr. _______.

I could make a joke here, but I won't. I'm better than that. Though I certainly hope you guys aren't.
Fireheart talks with his sister, reminiscing about the luxuries of kittypet life and explaining warriorhood to her. I appreciate that Fireheart specifically notes something that's considered foreign to pet cats and their litters, which is growing up with your family and bonding with them simply because they're your blood. Of course, once you remember that it's commonplace for cats to become orphans soon after or even before warriorhood, and that kits regularly become only children, and that he just acted surprised that she didn't feel closely bonded to him...
Fireheart leaves with the promise to see his sister again, which is just stupid. You got lucky one time visiting her, Fireheart. What happens if someone trails you, or if you come back smelling like the Twolegplace? We've already seen that cats have noses like bloodhounds in this world - your family reunion might be cut off super early.
But of course, this is our main character! Nothing's gunna get in his way if the plot demands it! Even Tigerclaw, the most suspicious of all regarding Fireheart, doesn't say more than "train with your apprentice tomorrow". That, I can barely believe.

OH FOR THE LOVE OF
Up next: Chapter Eleven.
