Answer: Damien. You may think it's Tess, but she would know about the flavor because your mom told her. But how would Damien know about it?
It's Thanksgiving, and your mom has enlisted in your help in making dessert. She has settled on pie, so the two of you get to work. You turn your back for one second before realizing a pie is missing from the lineup. There were 2 apple, 1 cherry, 1 pumpkin, and 1 blueberry. Unfortunately, the blueberry one is missing. You decide to go question your siblings and find out who knows something. They all claimed to be in their rooms at the time of the baking. You: Okay, who took it? We had 5 pies ready for the feast when everyone gets here and now we're down to 4. Any of you know where the missing pie went? Wendy: What?! You're accusing me? I bet you ate it. You probably couldn't resist and are trying to frame us again! Damien: I don't know, check in Wally's room? You know how much he likes blueberry and apple pie, right? Tess: I'm allergic to blueberry, you know that! Mom had to warn me so I wouldn't eat it when the time came! Wally: Come on, I may like pie, but do you really think I would sneak behind Mommy's back and eat it? It's pretty clear to you who ate the pie. You tell your mom what they said and she gathered them all into the living room. "Okay," she said to you, "on the count of three, point to who you think did it. I'll do it too. One - two - three!" You and your mom point to the same person... who did you point to?
