Choose Your Own Adventure (4/?) (Patreon)

You decide to accompany the woman to her family's farm. As you sit waiting for her to finish her meal she introduces herself to you. She says her name is Valentina, and she was currently in training to be a knight. Her parents passed away when she was a child and her aunt and uncle raised her and eventually helped her pay for knight school. When her aunt wrote her about the troll that had been pillaging their crops and slaughtering their animals, Val knew couldn't just stay in school knowing that the people that raised her and helped her pursue her dreams were suffering. The two of you finally set off towards the farm, which lay on the outskirts of the village. It wasn't a very big village so you get there in no time. Valentina's aunt and uncle greet her with a warm embrace and thank you for coming to help with their problem. Val's uncle explains that the troll was there just this morning and had killed three of their cattle. It had already dragged two away to it's cave in the forest, and would likely be back for the last one sometime soon. The uncle suggests you set a trap for the troll using the last cow. The aunt does not seem keen on this idea and suggests that you track it, using the cows blood as a trail. Which do you do?
