"Detention" is my favorite episode of the first season because of its central focus on the teenagers, for one day, in detention. I always enjoyed the truth or dare game because of the nonsense it created, and the basketball-to-the-face never fails to amuse me. The episode stands out because its the first to really build the relationships and conflicts between the characters. The previous six episodes barely had any scenes with Pacey and the others, and the scenes with the two girls and Dawson were all about Dawson's pursuit of Jen. Now, the characters finally hung for an entire episode and the audience understands the dynamic and conflicts between characters.
During the game of "Truth or Dare," Jen and Pacey kiss as do Joey and Dawson. Joey balks when she's asked which boy she's in love with. Pacey balks when asked how he got detention.
The kiss between Jen and Pacey affects Dawson because Pacey's represents everything Dawson lacks in sexual experience. His fears are relieved when Pacey reveals his embarrassing story of masturbation and Jen swears that she does, in fact, want him sexually..
The kiss between Joey and Dawson alerts everyone (but Dawson) of Joey's feelings towards her best friend..
