Final answer:
The provided excerpts do not contain enough information regarding the characters Alexis and David to determine where Alexis is thinking of going when David catches her.
Step-by-step explanation:
The question seems to be related to a scene from a play or script wherein the character Alexis is being caught by David in the lobby, and it is asked where she might be thinking of going. Unfortunately, the provided excerpts do not contain any characters named Alexis or David, nor do they provide sufficient context to deduce where Alexis is thinking of going. Therefore, without additional information about the script or the scene involving Alexis and David, answering the question accurately is not possible.
