The Final Act: Episode 13 painful icon time!! ( DONT REBLOG )
This scene is incredibly painful to watch for anyone that empathizes with sess.homaru’s previous home-situation (including his distant mother). through his eyes, he’s always felt as though his father didn’t trust him, didn’t believe in him, didn’t love him as much as inu.yasha. and in this scene, as much as he hates it, those feelings are confirmed and validated by Shis.hinki. He learns that the coveted Meido Zange.tsuha was originally a technique held by the Tessaiga, and that Inu.taisho found it dangerous and useless and cast it aside into tenseiga when he did not want it. thus, sess.homaru confirms that he was given a sword that was, not only to him but also to his father, completely useless. although this may not be inu.taisho’s true intention, it is how it is painted.
in reaction to this, he spars with inu.yasha and GIVES him the meido zang.etsuha, the tens.eiga’s only offensive ability. But this is only after attempting and failing to destroy both Tess.aiga and Tense.iga out of anger.
granted, this in no way shape or form excuses his deplorable actions throughout the series, but it is an insight into why he was so desperate to obtain either tess.aiga or so’unga despite his father’s wishes, as well as why he hated inu.yasha,
