Katsu bit his tongue and refrained from snapping at Siku, not at all appreciating her taunting behavior. His life hadn't been easy, not that he expected her to know, and the fact she was joking about it annoyed him to no small end. Did she know what it was like to not eat for days on end? To sleep on a bench in the park in the pouring rain? He doubted it, yet he wasn't going to sit here, get on a box and cry his troubles out to the world; she could go on thinking he was just complaining, he didn't really care enough to correct her. All of that was behind him anyways, and even on the run now his life was better than it had been. Rolling his eyes at the complaint about the restaurant, Katsu smirked slightly amused and gave a dismissive shrug, just to egg on Siku. 

"Food sucked anyways, too overpriced if you ask me," he responded calmly, looking away as though he were disinterested. Heh, two could play at that game, he'd rile her up just as she had him. When asked about whether he'd practiced other elements or not he answered honestly, a bit ashamed to say he hadn't yet seeing no reason to hide it. There was no need for him to, it wasn't like there was some great war or anything going on; aside from his problems with the Lotus defectors the world was in a relative time of peace, there was next to no reason for an Avatar to even exist. Seriously, if he only learned fire and nothing else then he should be perfectly fine!

Heh, water princess, he figured that was a pretty good one. Obviously he didn't mean it and made it in jest, but given Siku's sometimes haughty nature it fit. Chuckling to himself at her expense, Katsu gasped when he suddenly felt his support leave him, and soon was knocked to his knees with a rather angry Water Bender looming over him. Blinking just once when she began threatening him he glanced at her dao silently, doubtful she had any real intention of using it but not wanting to test his luck. Watching as she retracted the weapon and left him be, the Avatar breathed a sigh of relief before climbing back to his feet. "Jeez Siku, someone sleep on the wrong side of the ground last night?" he joked, rubbing at his neck before grinning at her cheekily, "You're kinda hot when you're mad though, anyone ever tell you that?" He really didn't know better it seemed, or maybe he was calling her bluff with her weapon being drawn, who knows.

"You said it, I don't care to master them. Why should I when I can use two already?" Katsu asked in turn, placing his hands into his coat pockets as he strode along. At least Asha was plenty supportive and not at all being a pain in the neck, unlike [i]some[/i] women of the group. Seriously, two days thus far and Siku had already threatened him twice, what gives? If she was going to draw her weapon on him every time they spoke then he'd just leave her be, see if she preferred that! She could have a pet rock if that was better for her, then he'd not be at risk of getting shanked for speaking.
