We knew that Romain had some connection to Vordin. But given he was able to use Drel’s voice and since Vordin had that connection to Drel it seems more likely that Romain is a pawn to Vordin like how Alicia is a pawn to Klen. Granted how Klen operates is more forgiving than Klen.
Alicia is always enduring and ironically that becomes her skill. The more she endures the more powerful her strength is. Good to see her smart enough not to fall for the trap by Romain/Vodrin. Although Alicia finds herself in another bad situation.
The one thing curious about Zavthier out of all the Dark Beasts is that she definitely is the most humane among them.
