quick Flash question

I've just read Flash #106, and I'm wondering, this James guy who's with Piper, when they and Linda meet for lunch, is he Piper's boyfriend? And who is he anyway? (When Piper says to Linda that he's no expert on relationships James interjects "Oh, I don't know..." and in this conversation it seems he and Piper share a house.) And who is he anyway? I couldn't find a James on the main site I use to look up Flash info, besides James Jesse, the first Trickster, and that guy looks very different, e.g. Trickster I has long blond hair.

Rainbow Raider?!?

Who comes up with these kinds of "supervillains"?? Okay, so they're called "Rogues" in Flash comics, but still -- Rainbow Raider?!? (also notice Trickster's fearsome rubber chicken, which I suppose could be some kind of deadly weapon in disguise with Trickster, and yet, it looks very silly nevertheless)

And just when thought that this had to be a low for villain names, I get introduced to one called "Crazy Quilt". WTF?

In case you're wondering, where I came across these... um... colorful characters, I'm reading Underworld Unleashed.
