Was is das?

Is this a creeper or a weed? I found it as a tiny shoot in the front garden, near the star jasmine, and I whipped it out, all excited that it was a creeper. But - is it? I don't know yet, so have potted it in this pot for a while to see how it turns out. It looks promising. Will see what happens. Slow growing at the moment.

The succulent (on the right) needs to be repotted, into its own pretty pot.
