I wonder... Does it say more about Tai or about Dora that she was sure her confession had messed things up? Either Dora must have really, really either kept her feelings locked up tight or Tai must have had a seriously strange idea about what Dora wants from a relationship for her to actually think that telling Dora that she loved her was a mistake! I guess that's what being in too many emotionally-divorced relationships do for you!
I take it as saying more about Tai and her history of hookups with folks who most decidedly wouldn't have welcomed such a declaration. Tai spent a lot of her dating life keeping her romantic side under wraps for the most part, and getting burned when she let it show. I think it's still sometimes hard for her to believe that someone
would love her instead of just liking her for a fun time. Remember how flabbergasted she was when Dora called her "my girlfriend"?
Tai's face and body language as she goes through her little freak-out is so well-drawn. Panel 3 cracked me up.
Re: Tai's weight, that could just be part of Jeph's style shift. The characters have gradually gone from highly stylized super-skinny figures to more realistic ones, and in the course of that, their bodies have become more differentiated from each other. Some, such as Dora, have remained on the twiggy side because that's
who they are instead of because it's
how Jeph draws humans. Those who haven't been deliberately cast as thin characters have filled out. Faye finally truly looks like the junk-in-the-trunk girl she's been known as from day one. Tai has been differentiated as a basically average figure next to Dora who's known to be skinny.
