Hideously:

It should have been a sight to which he reacted hideously; the woman he loved in another man's embrace. Yet Anakin could not deny that there was a rightness about what he saw, even as it sickened his soul. He should turn away, he knew he was intruding upon a private moment, that this embrace was an intimacy he should not disturb. But the Force stayed his feet, wordlessly whispering to him that there was something still to learn.

Suddenly they turned, beckoned him forward as a priest emerged from the shadows. An honour, he realised, to witness their vows.
