i have a feeling that particular dick didn't even show up. sensei seemed to be aware of the love triangle involving her students. maybe hitomi revealed it to sensei since she might got a clue about sayaka's fate. if this becomes a public knowledge, at least inside the "civilian" classroom, then hitomi might regret her confession and partly feeling responsible for saya's death.
hitomi, being an aristocrat who puts premium in public image and opinion, laments over the death of her friend in private but avoided personally visiting the necrological service because of shame, guilt, and buzzing rumors.
meanwhile, the bastard acting like a man for once, feels to stand by hitomi's side and comfort his new girlfriend. what's an old childhood friend now gone, if he has a new girlfriend between his arms?
besides the bastard doesn't have any face to show. who know, i maybe wrong. who would have guessed that the bgm was played by the bastard himself!
