As Nick said, Lucy was physically near Loke, so she could save him.

Aquarius was forced to go back to the CSW and she likely can't appear in front of Lucy on her own accord when Lucy doesn't have the necessary Key. Therefore, Lucy can't reconnect with Aquarius that easily.

Maybe Aquarius will somehow end up with Yukino and then be transferred back to Lucy along with the 3 Golden Keys Yukino already has (Yukino losing/transferring her Keys to Lucy is bound to happen at some point).
