The Essence of Cleveland - S2-E18
Continuity mistake: When Cleveland takes the tape out the camcorder, he starts writing. In the first shot, he's only just started writing, but in the next shot he is at least 70% of the way through writing. (00:12:00)
Answer: In the episode "A Rodent Like This" Rallo discovers that Cleveland Jr. is actually a secret agent who is tracking down Tim, who is actually criminal. Jr. reveals that in order to get close he had to eliminate the real Cleveland Jr. luckily Cleveland doesn't pay attention so it was easy. Whether or not this is canon or not depends on the writers.
