Oh, @Rune:
1. Reasons are: You're into MLP- whilst I know there are female fans (I'm friends with one), the vast majority of bronies are, as the name suggests, male. Furthermore, there is still the 'god-king' thing, although following your explanation this has been significantly lessened... I also believe it because you have a female character who is hot and into both guys and girls- but so far, mainly girls. It's more likely that you're male and so have somewhat large author appeal in doing this, than that you're female and bisexual/lesbian. It's also, sadly, more likely than you doing it out of wanting to create a good character; probability outweighs you there...
2. Regarding the headphones: exactly. So if Grimm wants to get her attention, that is one sure-fire way to get it...
Although if he wants to get some 'intelligent conversation' he should probably give up and start talking to Thane or Virus (or, I guess, Mindwarp), as they seem to be the only non-batshit insane psychopaths within walking distance...
