Can you give me a breif description of the first two episodes?

Because to me, episodes 1 and 2 seem like they are completely different, like I actually downloadded episodes 1 and 12.

In episode one, Ginko brings back the young version of Biki's (is that his name, I forget) grandmother (kinky, trans-space and time incest?).

But in episode two, Ginko saves this girl's eyesight. Sui, I believe.

Am I on track? Did I just watch episode 1 and 2, or did I download the wrong ones?

THANKS!
