Yes, sadly, little Grogu is not with his dad, and part of Din misses him badly. Though right now, it's been pushed to the back of his mind, to focus on the here and now.

Din's never seen a Jedi in Jedi robes. So. No. He's definitely not recognizing Ezra as a Jedi right away. However, the asking about a lightsaber is enough to clue him in. Only Jedi carry the things...and him. But that's a whole another story.

"Are you a Jedi?" Comes his own question in return. Sorry Ezra, Luke and Ahsoka didn't wear robes, except for their cloaks. So the robes is a new thing to him. However, before he can answer about the darksaber. There's another person literally crashing their little party. Din's right hand moves instinctively to his holster, even if he doesn't draw. But then he's relaxing it. Another new face?

"You alright?"
