could it be a chilli?!

I also thought it might be a pepper of some description.

I also thought a pepper of some kind. they do have quite variable leaf form did the first seed leaves look typical of a pepper or tomato?

I hope so. I love chillis. Yes the first leaves do resemble tomato leaves. You can still see them in the photos. I do have chillis growing in other pots but they don't look like this. Will let you know. Thanks everyone
