[Haise finds himself both relieved and pleased that Achilles accepts the offer. When he sees for himself what Olivia is learning, it'll be good for him to know what's been going on — and he can assess and weigh-in with his own experience. That ought to be a great benefit to Olivia as well]

Great! When we're back in Oska, let's find some time that works for you both, and get a training session in. She's a very able student, though I'm sure you're already well aware of that.

[Olivia had proven better at mimicking movement than Haise might've assumed of anyone, though given her poise he supposes that's not surprising at all]

And I can prepare some lunch afterward as thanks.

[After all, Achilles is doing him a big favor participating in training]
