Red Prince + Free Amyro

I couldn't find a precise guide for this online, so I just wrote one up.

Here's a step-by-step guide to advance in the Red Prince quest and free Amyro (and theoretically finish Sebille's quest after by killing Stingtail at the end):

You'll need at least two characters. One with at least 1 point in Thievery.

1) Do not initiate a conversation as the Red Prince with Stingtail (very important).
2) With your 2nd character, steal the Unusually Large Orange from Stingtail while he sleeps.
3) Give the orange with drudanae to Griff as the Red Prince.
-- SAVE HERE --
4) Follow Griff as he walks to the jail to free Amyro.
5) Initiate a conversation with Griff the moment you're able to has the Red Prince. Preferably facing the opposite of the jail cell.
6) Have your other character sneak behind Griff (wait for Waltz to climb down to allow thievery).
7) Take as much overpriced drudanae as you can (I'm not exactly sure, but I think 2 of them are needed). The orange's useless now.
8) Leave the area with both characters back to Stingtail.
-- SAVE HERE --
9) Defeat Silence who's about to kill Stingtail.
10) Once Silence is defeated, Stingtail will thank you for saving him.
11) With the overpriced drudanae in Red Prince's inventory, you can now initiative your first conversation with him, and he'll accept the overpriced drudanae instead of the orange for the dream.
12) At this point, you have freed Amyro and you have advanced Red Prince's quest. You can kill him now with Sebille if you desire.

Interesting to know, though it seems like a lot of work to go through for an optional objective.
