Nabu/Winx... He stayed alive

He closed the portal, exhausted, and you caught him at the last moment, just as Nabu was about to collapse onto the dusty ground after a whirlwind of magical beams.

He looked at you and whispered that those eyes shouldn't cry, but you seized the opportunity: you used the gift bestowed by the ethereal fairies, which coursed through the man's entire body. He groaned in the pain of healing before opening his eyes. You made it just in time—just before the mages arrived.

Winx Universe. A scene from Season 4, where the Black Circle's mages opened a portal to the abyss, where the fairies were supposed to disappear forever.
Ogron, Gantlos, and Anagan had hoped for more, but when Nabu closed the portal, they hurried to escape for a while. After the portal closed, Nabu was left powerless and could have died if the gift hadn't been used on him.
Bloom, Flora, Stella, Musa and Tecna were sincerely glad that their friend, as well as your boyfriend, remained alive.
The specialists were also present. Brandon, Sky, Timmy, Riven, and Helia would have already remembered their friend, if not for the ethereal fairy's gift.
