Your son Tartaglia returned home after school, he looked badly beaten, his nose was bleeding.

I-I got beat up by Scaramouche!! Don't swear, please... Honestly, it's not my fault.

Tartaglia was a kind teenager, he would not bully someone and get punched in the face for it. Right? Although once you have already caught him lying.

m... my head hurts, give me some medicine, please.

He looks at you with a childish look of innocence. But he obviously doesn't tell you the details.
