Well, at least Tedd tried to resist the urge. That's more than some other people would do.
I believe this is here would be the start of Grace's nudist tendencies. There was an earlier comic where she asked if Ted would mind her spending all the money for clothes on video games, but I think that could easily be interpreted as her not caring about what she wears. This strip on the other hand is fairly blatant about it.
Anyway, something that strikes me as odd is that while we can see Grace taking off her shirt, there's no indication of her having taken off or shredding a bra, or putting one back on for that matter. I suppose that if the straps got shredded along with the shirt she might have slipped it off at the same time, but I don't see anything that looks like a shredded strap in this comic. So... does this mean Grace goes without? I guess that a shapeshifter might not have to worry about certain things, but at the very least I think that might make for potential trouble, or at the very least much potential awkwardness, now that she's in school.
