Translation of "Invariably" in Spanish

It's emotion that invariably wins.

es la emoción la que invariablemente gana.

And the answer, that I almost invariably get is --

Y la respuesta que casi invariablemente recibo es:

Mary invariably brought more food than she could eat.

Mary siempre traía más comida de la que podía comer.

And even if you think something's free, it invariably isn't.

E incluso si piensan que algo es gratis, invariablemente no lo es.
