Knew It All Along

A lot of times in life, lots of people jump to conclusions about certain kinds of things. After a little bit of misunderstanding, once a character finds out what's really going on, he will then proclaim rather blatantly that he knew it all along.

A Comedy trope that you can expect to see in media, and I knew it all the time.

See also I Meant to Do That and Glad I Thought of It. For when people actually knew it all along, see The Not-Secret.

Not to be confused with I Knew It!, an Audience Reaction.

Gerard: I knew it was an elevated train.
