Pampered 'aubergine'

In late spring, my friend Kyri gave me an aubergine (eggplant) seedling from his greenhouse.  I placed it under a cloche surrounded by other seedlings on the patio.  On cold nights, I worried about it's ability to survive and even considered placing a hot water bottle by it's side.  Anyway, it pulled through and gradually this handsome plant emerged. Anyone recognise it?

By mid-summer, I was ready to give up on my aubergine plant.  It was grown in a luxurious pot and fed copious amounts of potato fertiliser but the fruits were minute..... 

The smallest ripe 'aubergines' I've ever seen..... 

Finally a call came through - the 'aubergine' was actually a weed!

P.S.  Kyri also gave me a pepper plant.
