I don’t think I ever really gave much insight as to why I’m not a big fan of F, so what the hell, here goes:
Keeping in mind that F is from another world and basically had to be taught human mannerisms and speech in order to even function on Earth, I still say the fact that they have the tendency to just mouth off at the first excuse, whether they mean to or not, is a big dent in my approval of them. Granted, their main company is Unit Bravo, who are also somewhat lacking in social graces, but still, you’d think after enough missions that they might have learned better when to pipe down - if not out of respect for the individual they’re speaking to, then at least for the sake of not damn near blowing their entire mission out of the water (book one, once again).
Then there’s the much more obvious “never stops flirting, even if it runs the risk of crossing boundaries.” If your first instinct when we meet for the very first time is to try and troll me by going in for an uninvited kiss, I’m probably going to slug you. The joke ain’t so funny when you’ve got a sore jaw, I’d imagine.
To immediately contradict what I just said, if you go no romance at all, suddenly the flirting ceases outright, which I’ve mentioned previously to be just a tad too unrealistic, even for this particular character. But that’s more to do with the author’s handling of the romance mechanics in general, rather than a quirk of F, particularly.
I also don’t like that F is so eager to goad people into starting drama with each other. Even if they view it as a funny joke to see two people bickering, I certainly don’t, and I don’t appreciate them constantly trying to drag my detective into it - in particular with regards to shooting A on first meeting. My detective was legitimately concerned that she was about to get attacked by four strangers, acted to defend herself… and you’re laughing. Seriously? Seriously. Even if you don’t take my actions seriously, consider that I just shot your teammate without hesitation. That doesn’t concern you at all? Because it should, superficial wounds or not. That, if nothing else, is a firm reminder of what you risk by exposing yourselves, I should think that, alone, would be enough of a warning bell for you.
So, yeah, I’m not F’s biggest fan on account of loose lips, lacking social graces, and a propensity to not take shit seriously that they should be. However fun a person is, if they treat their job like a comedy act, I have very little faith in them.
Now, granted, a lot of it might also be a coping mechanism for their own personal drama (going no romance gets you stuck with F as your buddy by default when you go to the fair for the first time in book two, you see), so I can be persuaded to forgive it to a certain degree… but at some point, you gotta just hold the character accountable for their own crap. So, for me, that means that F sits squarely in the, “I don’t hate her but we’re also not friends” box.
