John can cook

As john entered the cave, he found Serena awake, she was still laying on the ground and was still red, but it looked like she was feeling slightly better 

John quickly took the crate with medicines over to them and released posession 

"welcome back, john" Said Ariel 

"Thanks Ariel, Is serena feeling better?" John asked 

"Of course I am" replied serena as she looked away 

"That's good, I went ahead and got you some medicine" Said john as he placed the crate on the ground next to them 

He got the medicine master told him to give to serena, it was in a closed liquid bottle, John checked to see if it was used, and it looked like it hadn't been opened so he felt safe giving it to serena 

It was most likely something the bandits stole and never got to use, but just in case it wasn't poisonous, he planned to try some himself 

"Where and Why?" Asked Serena as she turned to him
