Gundam Wing - Ep06 HD Watch

"Party Night"

Relena returns to school in time for a dance, but discovers Heero is going to transfer. After she reveals she knows all about him and his mission, she persuades him into being her escort for the dance. However, the school is attacked by OZ mobile suits sent by Lady Une to kill Relena. Heero uses his Gundam to fight back (believing the enemy suits have come to get him) and ends up saving Relena, much to his own disbelief.
