And it doesn't look like Devyn or Abby has grown very much in the last two years, though apparently Alexis has . . .

Personally, I thought the first panel had Alexis walking towards her desk, while Devyn was already sitting. In the second one, Abbie has had time to come over*, and they're probably now standing.
* Implied by Devyn's statement, that Abbie is also there, which would be unnecessary if Abbie had been next to Devyn the whole time.
Of course, I could also be wrong, and Alexis really shot up, compared to the other two.
But after a slight search, I find that
Alexis was already taller than Devyn a while back... And considering that girls typically reach their adult height sooner than boys, they may have already peaked before we met them, and their heights has remained more or less the same since.
[Edit]
Today's comic confirms that Alexis is indeed still taller than the other two, and they were all standing, all along (since no one had taken a seat, yet)... But my theory that Abbie was not immediately next to Devyn is probably still correct, because Devyn would not have had to mention it, had Alexis been able to see Abbie next to Devyn.
