The Elvis Presley bit between Devon and Cornwall at the close of said acid sequence:
Cornwall: (In Elvis' voice, to Devon) Hey, you've never sung before, have you?
Devon: (Sucker punches him in the face)
Kayley: Do you hear something?
Garrett: No, I just want you to be quiet for a while.
When Ayden the falcon snickers at Devon and Cornwall's failure to start a fire, Cornwall just eats Ayden without much preamble. "I got three words, birdie; Dinner-Is-Served!" Luckily, the falcon escapes by flying out of Devon's mouth!
Kayley pesters Garret to allow Devon and Cornwall to come with him. Eventually he agrees, but only on one condition: "No more singing!"
When Bladebeak beats up a guard, his hen wife (?) looks at Juliana as if to say "That's MY man."
