Thoughts?

I know that it’s in the side stories now but do yall think they might have a third kid? The title picture features both the twins in human form and two snakes. One of which likely represents geumryang, but what about the little one on taesung’s shoulder? He can’t turn into a snake and I feel like it would be two little ones if it was gonna represent the twins. Plus at the end of the side stories in that last drawing with the deer, it is attached to the basket, do it was intentionally added. There is no big snake to represent geumryang in that drawing so.. what do we think?
