We'll post a detailed recap of the episode, "One Party Can Ruin Your Whole Summer," soon after it ends. For now, here are a few teases to get fans excited for the season-ending installment...

• A couple gets high.
• A new crush develops.
• Brenda comes back... twice!
• Navid and Ty make amends.
• A character is dragged away in the middle of the night.
• The name "Zelda" plays a key role (and we aren't referring to the video game!).
• Silver kisses... someone.
• There's a possible hit, a possible run and possible serious trouble for a main character.

Does Brenda get Adrianna's baby, as man fans have speculated? Tune in tomorrow night and find out!
