You mean "Message in a Bottle". A fine episode to be sure, I thought the way the two EMH's played off eachother was great, and I feel the idea was more original than Timeless which was the usual time travel hijinks with a twist.
Message in a bottle so funny XD and yet had some real original aspect to it. Also timeless was good the 100 episode they really tried to make it uber and i think it worked.
Deadlock was the best thing along with basics in the first 2 seasons for me.
