Pausing here for a moment since I missed a post that suggested moving on instead of lingering, and Sudo's asked some good questions.
If you check
here, you'll recall that you spent the morning in town, and didn't get underway until about mid-day.
It was only about an hour of straight travel to Vivians, but you stopped at the abandoned farm, talked with the nixies, spoke with Vivian... let's call it now mid-afternoon. Technically, by Cairn watches, it is
Afternoon. So, less of a time loss than you might be thinking unless you were planning to travel after dark.
Still -- it's your call. My erroneous read was that you were going to see what she could do and stay briefly. I'll let you know now that straight / instant magical healing is a rare, rare thing in my OSR games. Vivian's care would help, but take time -- like several hours or ideally overnight.
Regarding Vivian's reaction, she's a batty old lady. She neglected to mention anything other than 'have at it!' She just probably doesn't remember it that way.
So -- what's the plan?
