So, the line that piqued my interest was his response to Moxxi asking about any previous relationships: "THE TINY ONE AND THE SAD-FACED MOTHER AND THE BLUE TATTOO FOREVER AND EVER!"

Now it's pretty obvious that he's communicating Krieg-style that the three ladies he's "cared" about are Tina, Maya, and (who I believe to be) Moxxi. The part that's got me confused is that, while it's canon that he likes Maya, and the Tina reference is just Gearbox being Gearbox, why the hell did he mention Moxxi?

Did I just miss something in my play-throughs? Is this going to expand on Krieg's past? Is it just because Moxxi is pretty much the only reason that BL2 has a "sexual content" tag?

I got nothing. So maybe one of you can see something that I'm not.

Tl;dr: Gearbox's OTP is Krieg & Moxxi?
