She's already looking forward to it. 

But - she'll let Ellie get back to her business for now. 

"Thanks for the books."

"No problem."

"Until next time." And Ellie will take her leave.

Next time rolls around soon enough, and Ellie shows back up to meet Lily and James. She was thinking that they might want to do something a little more active than chat in a pub this go-round.

What does she have in mind? 

Have a bit of fun showing off magic to each other. Stretch their wings, as it were.

Ellie might need to pick the location. 

How do they feel about an off-grounds excursion?

Sounds like mischief.

They can manage mischief.

Well then, if they'll both take her hands for a Side-Along?

Of course. 

Then Ellie will whisk them away to a nice stretch of deserted coastline, with plenty of open space.

"More private than a pub, too."

"That's the idea. Don't want to give away all my tricks."

"I'm honored to receive your tricks, then."

"I bet they're impressive."

"Oh, I don't know. I hear you're supposed to be an animagus yourself."

"She'll show you hers, since you're so graciously showing us yours."

"Very considerate."

"Who should go first?"

"We could flip for it," James suggests.

She's got a coin. 

Heads James, tails Ellie?
