To be fair, it's not like Obi-Wan could have known that there was a land mine there to avoid. He doesn't know the situation Ezra last saw his friends in, and Ezra doesn't see a reason to bring it up right now. Better to focus on the present, on the things he can do something about.

"I... Thanks." He stills, then hesitantly smiles. The brief touch on his shoulder is a gesture that's relatively rare in his life, and mostly comes from Kanan, but from a Jedi Master? Maybe that's not something to mind, even if they did just meet. The offer of assistance is appreciated, too, though Ezra would like to think he doesn't need it. "You can call me, too, if there's something I can do."

A pause, a hesitation, because traditional Jedi greetings and farewells are still new to him. Then he lifts his hand in a very brief wave.

"May the Force be with you, too."
