I postulate that if Odo was better able to mimic humanoids, he would just be disguised as Morn or Rom all the time to fuck with Quark.

"Harumph."
"Did you just...? Dammit, Odo!"
Maybe Odo was Morn all along!
It's relatively new. The book it came from only came out in 2005. My daughter begged us to do it. Thankfully only for two years. Every day you're supposed to find a new place to find the elf and they're supposed to find it. Which she couldn't do without basically guiding her to it.
