Erect Rhizomatous Begonias

I bought a rhizome begonia from Jesse Durko's a month or so ago. I've been very excited to see how it's going to grow. There are 2 large stalks, will they just keep spitting out leaves going higher to just be leggy rhizomes. I noticed a small leaf at the base of the stalks and it seems that another rhizome is being born! I'm thinking that rhizomes might actually come out of the side of the erect rhizomes.

When I bought it was in a plastic pot, packed with a good deal of vermiculite keeping it too damp i think and the soil on the top was tight with roots. I repotted with looser soil and broke up the roots on the top.
