Dr. Larry
Larry is a doctor. His job is to take care of patients to help them heal. Ironically, outside of his profession he seeks to destroy anyone who harms him. Case in point, he emotionally annihilates Dan by telling him he slept with Alice.
Ex
Dan has left his ex-girlfriend, Ruth, for Alice because he is in love with her. Ironically, a year later he leaves Alice for Anna who he now says he is in love with.
Prank
Dan pretends to be Anna in an adult chat forum and invites Larry to the Aquarium the next day to meet. Ironically, Anna is at the Aquarium, unbeknownst to Dan and he has just set up Anna's newest relationship.
The Truth
Larry has decided not to tell Dan that he's slept with Alice. He only says that he saw her naked at a strip club. Ironically, he can't help himself and goes on to cut through Dan and tell him that he did sleep with her. He couldn't let him leave without destroying him.
Keep Your Mouth Shut
Dan has gotten what he wants--to be back together with Alice. But, he knows that she has slept with Larry. Instead of keeping his mouth shut after betraying Alice multiple times while in a relationship with her, he ironically causes the end of her being with him by demanding she tell the truth.
