Part of Luke's very not Jedi upbringing is that there's a strong urge to give Ezra a hug, because that's all he really knows about coping with grief and loss. You hug, cry, and then move onto whatever you need to do next.

Instead, he squeezes Ezra's shoulder. "Ben was never really my master. He was my guardian, but I think in a way I felt a lot closer to him than I did the Jedi who actually did most of my training and declared me a Jedi. And of course, he still hangs around even now he's dead."

And decidedly the least weird of his Force visitors. He at least talks to Luke, doesn't just stare or run off when noticed.

"I know of Lothal. I've never been, but I know about it. Outer Rim world, one of the few Imperial strongholds. I'm sorry you can't go back. You might not want to, but not having the choice is hard."
