Implied odds?

[DRD66]

I thought this was easy when I played it, but now I'm not sure. No reads, first hand at this table - GT+ not opened yet.

I know I don't have pot odds to call this, but in retrospect I'm wondering if I had implied odds? If the king falls, I should clean up on the river. How do I think this one out?
