Also, this is why the airlock isn't a gauge of fermentation activity or 'doneness' of beer. Its just a CO2 vent, and that's all you can rely on it to do.
I know its tempting, and sometimes it IS a sign of fermentation activity, but its just too unreliable.
Fruity smells could be the hops...if it fermented too warm it might have a banana or Juicy Fruit kinda smell, but your description sounds more like young beer and that hop combo, and possibly excessive yeast lending its smell too.
Give it time to drop a few more points and I think you'll be fine in the long haul.
