A former Seigaku tennis player makes a surprise appearance while Ryoma is training, inviting him to witness his match against Tezuka.  And before the end of the match, Tezuka’s secret will have been revealed and a life altering decision made.
I heard you demolished him 
when you were a first year.
Cuando tú estabas en el primer

¡Pero tú ya pudiste con él cuando estabas en primero!
Soube que você acabou com ele
 quando estava na sétima série.
