I hadn't really thought Mandalorian was connecting that much to Rebels until this opening episode (and the callback is subtle enough that any non-Rebels watchers will probably just wonder about it). LOVED the callback though!

Of course Mandalorian can technically connect to most of SW lore and canon, especially since the final trilogy is yet in the future. And it does reference it in, say, what Ahsoka tells us but at the same time Ahsoka herself starts much earlier.
