in the sights
It's in the spotlight.
Espera a tenerla en la mira antes de disparar.
Wait until you have her in your sights before shooting.
— Nausicaä del valle del viento (1984)
I've got my eye on them.
I have my eye on her.
Ya tengo el blanco de nuevo en la mira.
I've got the target back in my sights.
I've got my eye on him.
