Bakemonogatari - 2x04 - Karen Bee - Part 4- Followmy.tv

Araragi tries to get Karen and Tsukihi to tell him about the incident, however they refuse and Tsubasa has to explain to him that while investigating Sengoku’s curse, Karen met up with Kaiki Deishuu and had something done to her. Later on, while in the bath, Shinobu suddenly comes out of Araragi’s shadow again and tells him that she recognizes that Karen has an oddity Oshino once told her about – the Wreathe-Fire Bee. The two end up reconciling, with Araragi realizing that if he has the lifespan of a vampire, Shinobu will be the only one left beside him after hundreds of years.
