[i]Poor Favlev; Thassa wasn't fair to him.[/i]
Certainly, if he hadn't brought fish, it would have been a considerable challenge to keep her eyes off the little chikorita. As it stood, she sampled the air with tongue, flickering, savoring the scent, [i]and the taste in the air,[/i] of fish. The serpent takes her time though, and she makes him wait, sliding up around the smaller creature and pressing her nose under his neck with a sanguine hiss. Because... [i]she appreciates the gesture[/i], she does, that a pokèmon whom she had earlier considered a potential meal was then willing to go out and find fish just for her. Could he even eat fish? ...Her head disappears into the bag; one fish and another, she swallows whole, but her feeding is not a swift process. She can't just... grab one and take bites out of it as she goes, after all. It was during this time that the rain would have started in earnest, while she leans against her rather unlikely companion. Favlev would, likely as not, feel each of the fishes as it slid down her neck. 

Finally, knowing full well what an ordeal she was making of simple food, she hooked her teeth through a third fish and turned to unwind; she let Fava go and swallowed her last fish before she turned to the road ahead - and, briefly, her eyes to the sky. "...I suppose I'll keep you around after all." She says, a somewhat playful jab after their first conversation. "...Now, you know how all this works, yeah? I don't really know who to talk to or how to form a team or how to... anything... in a guild. You can help with that?" 

Delays aside, the trip to Treasure Town was not an excessively long one; she didn't mind the rain, and by the time they arrived she had taken herself quite happily to slipping through the mud, submersing herself in the odd roadside puddle... she'd be filthy, except it was raining, and scales don't really stain!
