During our campaign this weekend we encountered an Ettin named Oinkers Boinkers. It had two heads (one head was Oinkers, the other was Boinkers), each with a different personality and it acted like two creatures in one body.

A sorcerer can twin a single-target spell to hit a second target that is different from the first target.

Legally, a basic Ettin is one target, I think, but the fact that I could say "I'm targeting Oinkers" or "I'm targeting Boinkers" suggests that there are two implied targets and a sorcerer could legally twin an attack spell to hit both heads but for their shared health pool.

Could a sorcerer act in this way?
