Have Donnel follow it with you
From Create Your Own Story
You point out the vine and the two of you folllow it into the forest. The longer you follow it the stranger you feel about all of this. Eventually you stumble upon a ginormous green bulb with many vines jutting out of it. What shocks you the most is finding a man completely naked and held in the air with a few of the pant's vines. Two differently colored vines were shoved down his ass and mouth. He was limp but still breathing. Most likely to have passed out from being brutally attacked by the plant. This must be what happened to the knight and judging by the way the plant started to pull him closer to the bulb if you don't act soon he might become plant food. What do you do?
