"Possibly essential."

"Almost certainly," 2B corrects.

"We can practice together before we hit Ronan, too. See if I can get up to 'hidden even when actively stabbing someone.'"

"That sounds like fun."

"Training together will be good in other ways, too."

"Improve unit cohesion."

"And we don't want to go into a fight like this unable to predict each other."

"Yes, exactly."

"I'm not sure the ship is a good place to spar, though."

"Not really, no."

Do they have somewhere convenient to stop? 

Ash doesn't typically roam around this close to Asgard.

"There's a lot in between here and the Nova Empire..."

"Think we should get a bit more distance from 'here' first."

"I know some places."

"Cool. Just need coordinates."

She gives them.

Then she'll set a course. Training grounds, here we come.

It's nearby a stop she uses for refueling - so, pretty convenient. It's only inhabitable like a quarter of the year thanks to an irregular orbit, but it's got a mostly breathable atmosphere and not a lot of people bother with it, which is great for her. She's actually got a good set of ranges she's built over the years, and some good areas for practicing. 

Then they should get to work, or whatever.

Probably start with solo demonstrations or explanations, then sparring? She wants to watch 2B fight.

Sure, that sounds fine.

Gamora mostly sticks to explaining her magic - even with Loki's help hiding, she doesn't want to risk drawing Thanos's attention if she doesn't have to. 

"Does that mean you're not going to use magic when it's for real or not?"

"I'll use magic against Ronan, but not lesser threats."
