In Season 2 Episode 21 "Through the Looking Glass", at the end of this exchange
Silas: And if we tell you 'silent' you shut your cow mouth!
Cordy: Pardon me?
Silas: Pardon - your majesty? Don't you feel you have done enough - pardoning......for one day?
Silas lifts the lid off the platter he brought froth revealing
Lorne's severed head
now looking at things currently it seems Pylea is sorta "backwards" to Earth where:
- humans are considered animals (cows) and the culture of the world is to enslave them
- Lorne's singing burns people (as indicated by his mum saying "It's Burns" when helping Angel escape by singing)
- Angel, having become some sort of Pylean Vampire equivalent, doesn't burn in the sun(s) and has a reflection
so, I am wondering, since to pardon is
the action of forgiving or being forgiven for an error or offence.
and in Pylea it seems even everything that is a crime comes with an execution, does pardoning someone mean something different in Pylea and it's all been apart of Cordy's misunderstanding (like how what she imagined the Groosalug to be); or was Silas's reveal to show that him and the other priests don't actually obey Cordy at all?
