Cato was the last to die in the 74th games. Brutus was the last to die in the 75th games.
Cato’s last kill was the district 11 male (Thresh) and so was Brutus’ (Chaff).
Both male volunteers from district 2 were killed by volunteers from district 12 (Cato - Katniss, Brutus - Peeta).
Look at her smile when Cato screams ‘Where is my knife’
