Well, given Kouga's father's personality and his grandfather's, I think Kouga definitely is doing better. Besides that, this episode makes Haitani's stance on the situation much better. Also, you start to appreciate Jin's ability to be level-headed and assess situations instead of going ham when anyone mentions that they are EVOL. Referring to the interaction with the "Master" ofc.
The Jin - Hanako relationship doesn't make a lot of sense to me. It feels quite forced.
