Reveal to Jen who you are.

"Jen, this is Dandelion." Liz says, excited "He was going north too, now he's going with us. He received a call to go to the Pond, like you. So we thought, why not?"

"What? A call?" she's confused and worried, but stays cool "What was the call about?" she asks.

It was a message about what's to come, about a prophecy, about the grass and the air, and everything they cover or touch. They said you were called too, whatever your calling was about... You make a vine grow inside Jen's armor again. You control the vine and direct it towards her pussy, where you slide it over her entrance slowly, just trying to tease and scare her ...I'm sure it was very important. She receives your message very clearly, it's noticeable on the shocked expession on her face. After a few more strokes you retract your vine again. After a few moments she's back to herself and says "Welcome to the team..." submissively, accepting the new situation.

"Now, I usually don't do this, but..." Liz reaches inside her bag and pulls out a few alchemy ingredients. She drops them inside the pan she was making food before then pours some water along with it. She mixes for a while and the ingredients quickly vanish in the water, leaving it a bit hazy. After mixing it some more, she takes a few cups from her inventory and fills them with the liquid before serving. "You guys might want to drink it slowly though, that's very strong" The hunter is the first to drink. As soon as his tongue touches it he shouts a very loud "LIZ, WHAT THE FUCK?" The healer laughs before sipping her cup too. She's playing tough, but she's feeling it too, making an almost disgusted face. The priestess and you go after her. Jen can barely take a sip, spitting some of it back. You can't even feel the taste since you don't have tastebuds, or an esophagus, but you pretend you do by shaking your head a bit, while letting it leak to the ground discreetly.

Liz notices you're almost not being affected by her best creation yet and says "Look at that, we have a professional drinker here..." To be honest, I never drank anything like this before. I think you guys are weak, actually... The hunter releases a taunting "Oooooh, in your face, Liz" making Jen laugh. Liz gets up, you can see she's feeling the effects already, and walks to you kinda tipped to the side, then says "Look here, Dandelion. I CHALLENGE you to a drinking competition, the winner gets a favor, which can be anything, from the loser"

You'll win. There's no doubt about it. You just have to choose what you'll want from her.
