Where are we?? I would think we would know where but it's so unfamiliar!
I'm not quite sure this island seems familiar at all!
Oh no! Not my poor Ferdinand! He is now lost and alone!
Curse that Prospero! We have lost so many of our men all because of his and his wicked storm! Matter of fact, where's Ferdinand?
What're you trying to get at?
You know what's a good plan...
As Sebastian, Alonso, Gonzalo, and Antonio get washed up on the island, they meet up with one another and begin to panic because of not knowing what to do and realize they have lost Ferdinand.
Ariel then comes along, plays a song which puts everyone to sleep except for Antonio and Sebastian. As they're the only two that are awake, Antonio tries to pursuade Sebastian into killing his own brother in order to become "great" again such as it did with Prospero.
Sebastian then is in agreement to what Antonio says and they both pull out their swords to do so.
Ariel then comes along and plays a song for Gonzalo to awake and he does, also realizing what is happening and tries to defend Alonso.
Gonzalo then remains suspicious of the two but chooses not to challenge them but to keep eyes on Alonso and his safety.
In my opinion, the greater value in someone can lie within virtue as it is more a foundation of principle and good moral being in comparison to someone that plots on getting revenge all due to not being able to move forward.
