We actually learnt a lot in episode 11, as Naruto finally gave his son permission to peruse this ghost.

We also will get to see why Mitsuki is so interested with Boruto, as we get to know a little bit more about the son of Orochimaru. But until then make sure to take a look at the preview for episode 12 of Boruto here below:
