I have to say I'd never even considered Jeannie Tirado as a possibility, but nonetheless, it's great to see one of the newest cast members taking part. I have a feeling that makes my idea about Zamasu's actor a bit more likely - assuming we're seeing a pattern here.
On that note, I'm not sure if we have two more left, or just one. I have a feeling Jeremy Inman was added after I was made aware of the surprise guests and their number.
