RDWHAHB. Just toss the airlock on there and give it a few weeks.
If you used bottled water, it should be pretty close to sterile, so there's not much of an infection risk. You will probably rouse some yeast into a reproduction cycle. I believe that's what will happen, but it's no big deal- I'm guessing it'll probably just take longer to clear.
You shouldn't do what you did, as you know... but I doubt the results will be fatal.
Bill for this consultation: 1 beer.
