Mild spoilers for The Legacy of Mandalore, season 3 episode 15 of Star Wars Rebels, i suppose.
There were some spoken bits of mando'a in the beginning ! Here's what i heard. When Sabine sends a message to let the clan know of their approach...@ 0:56
Sabine: Su'cuy, aliit Wren. Ibici Sabine Wren. Ara'novar. Gedet'ye me'vaar ti gar?
The reply: Elek, Sabine Wren. Ke pare.@ 3:26
After a small firefight, Tristan says "Sha'kajir!" to his team.
Unless i misheard a word, ibici seems to be a verb form of ibic, which is pretty handy. Has that been used in any canon before? It's not in Karen's dictionary, as far as i can see.
This episode also gives a look at some of the politics & status of aliit Wren, Mandalore's situation with the Empire, and a lot of insight into how Sabine is dealing with her personal & family identity... But i'll need to rewatch to formulate some real thoughts on those :p
