I noticed, post-Movie, Carly spends very little time with Daniel (or Spike). They attended the Galactic Olympics together. Carly went off searching for Daniel when he was missing (though her tone seemed more annoyed/inconvenienced than worried). She remained silent when she and Spike went to check on Daniel while he was having nightmares. She's absent from most of Daniel and Spike's adventures. She didn't attend Daniel's birthday party. Perhaps it's telling that Daniel called for his dad during his nightmare. Although, I wonder if the princess that Daniel dreamed up was based on Carly.
