Quote from : The Lord of the Rings: The Fellowship of the Ring Movie

Aragorn: I swore to protect you.
Frodo: Can you protect me from yourself?
[holding out the Ring]
Frodo: Would you destroy it?
The Ring: [whispering] Aragorn... Elessar...
Aragorn: [closing Frodo's hand around the Ring] I would have gone with you to the end, into the very fires of Mordor.
