Saffron isn't far from Sam, and when he drops to the floor, she darts quickly around the edge of the trap to his side, though she's not sure what in the 'verse she can do to help him. There are tears standing in her eyes as Castiel calls for the exorcism, and then Neil shouts her name, but her voice is steady as she starts the Latin.

She was alone last time, but now Sam is here too, to say the words with her, make them stronger. This time it will work.

"Exorcizamus te, omnis immundus spiritus, omnis satanica potestas, omnis incursio infernalis adversarii..." Still beside Sam, she stands facing Dean and the rest as she says the words, loud and clear.
