Unknown seedling

I found this evergreen growing near a treetrunk last spring so I potted it up and forgot about it. Eight months of neglect later it looks like this - which is nothing like anything in my garden or what I can see of next door. Suggestions please?

 

Opposite leaves...might it be Fuchsia?

 

I thought fuschia last night, but thought no, can't be.

 

It does look very much like a fuschia.
The only other option that springs to mind is some sort of lonicera
