I.D please?

This little plant came along in a pot that had my azalea in it, so when I repotted the Azalea I chucked this in it's own pot. It had one small leaf at the time and has taken off!
Any ideas?

Thanks

It looks really familiar to me, but for some reason I cant quite work it out. Maybe it's a wax leaf begonia ... if it is then it will grow pretty quickly and flower.

Looks like a wax leaf begonia to me too.
Have a few that have self seeded in pots out back. They grow pretty quick. Snails don't mind them. Has small pink flowers.
