Opinion: I don't think Callum plan would have work anyway.

In season 7 finale Callum deciding using dark magic to capture Aaravos in a coin, and then allowing someone to kill him so he won't be used as vessel to Aaravos, sound like smart plan right?

The thing is, it just don't make any sense it would work considering the Situation.

Aaravos literally smiled when callum started the spell(even when the one that needed to kill Callum was Rayla, it's still doesn't make any sense, it's just doesn't fit Aaravos personality and as character), it doesn't make sense if it mean he will be trapp in a coin forever.

Not to mention that Aaravos could just telekinesis to kill Callum and make him fell from the place he was(if hebwas truly scared Callum plan would have work). If Leola could have doen it, the master of arcanums himself should easily do the same, like he did with the bird.

Also the show always make it seem that the prison that trapped Aaravos was extremely powerful and unique, now Viren coins are also catble way to imprisoned Aaravos? It mean anyone that just using dark magic can imprisoned Aaravos, maybe sacrifice their life in the process, but still.

I don't know if it just me but I think that even if Avizandum wasn't stop the spell and attack Aaravos, Callum still wasn't succeed in the spell.

• I know we see the spell start working on Aaravos but I believe he will never be able to finish it anyway and he will still die/be corrupted in the process.

But what are your thoughts? You think it make sense or I just assuming too much? I simply don't understand how his plan would have work and Aaravos would let him to do this knowing what will happen.
