I think 3 looks most promising for a new shoot. The other 2 look like new roots. Could be wrong. Just my opinion. I would leave it like it is. What is that little white thing in the first photo? That looks like a little brush?
This is my Aurea...all I could save of my old plant after a greenhouse heater mishap, but currently very happy. It originates from the edge of my stream, where it was planted under a flat rock. It has made it across the streamed, so I gave it a branch to start climbing back up. Adventitious roots have clasped on already. There is a 12 foot totem attached to the far end of the branch for it to climb when it gets that far.
