Vultus est index animi. The face is the index of the soul. 'Index' here has the meaning 'informer or discloser gicing the literal meaning 'the face is the informer of the soul'. An equivalent is the 'eyes are the mirror to the soul' or 'the eyes are the window to the soul'.

Alea iacta est. The die is cast. Spoken by Caesar when he was about to cross the rubicon - from which the English 'to cross the rubicon' originates.

Crossing the rubicon is comitting yourself to some undertaking, normally hazardous in some way and which can't be undone.
