Tai is annoying and one-dimensional. Just figured I throw that out there.
What? How is being a eighty pound exotic looking horny librarian, who drops acid, gets stoned and drunk, chases tail, is smarter than your average --err girl?--, witty, cute, willing to learn new things like rope tricks you can't show mom (unless you're Marten and then only to make sure you got the knots right), wants to be loved and wants to find the right one, but plays loose and wild meanwhile one dimensional?
Predictable? Maybe...but not one dimensional.
She's cute and bouncy like a new puppy. And another potential wedge between marten and his girlfriend...
It's more likely that she'd stray before marten did or try and invite Tai into their bed for a menage...but Marten has to work with Tai and is too honest and a good guy to really consider that.
