I'll make it quick for your sake.

[That isn't reflected in how he sinks to his knees, reaching out for the Captain's hands.]

I missed you too, darling. I'm sorry I didn't give you a proper ring when I had the chance. I could have protected you with it. A mistake we'll rectify once we're gone from here.
