A few extra lines at the beginning of the final scene in Friendship one:
<Chakotay and Janeway in Carey's quarters>:
Chakotay: Captain, I was thinking .... we have the means to give Lt. Carey a mechanical heart... also, he's only been dead for a few hours and his brain wasn't damaged at all... why don't we simply use those nanoprobes of Seven that resurrected Neelix, too ?
Janeway (clearly unwilling): That was a few years ago, Seven has become a lot less Borg since then.
Chakotay: But her nanoprobes are still working fine Captain, she even used them mere hours ago on that alien to cure his radiation sickness.. so I don't see why we couldn't use them on Lt. Carey too ...
Janeway: Now you're just being silly, Commander. We'll speak no more of this.
<rest of the scene plays out exactly as we know it>
Janeway (addendum): Besides, I can't stand him, if B'Elanna hadn't punched him in the face I might have done it myself.
