Redemption.
Elk couldn't do it any longer.
It backfired on her, of course, because, after all, these guys couldn't be trusted. If they could be trusted, they wouldn't have set her up in the first place, now would they?
However, she just lucked out, big time.
Not only is Our Hero there to save the day, it appears he was there long enough to hear everything.
Which means... not only does he now know that she was using him, setting him up, he also knows that she couldn't do it any longer and live with herself.
And that means...
That after he rescues her, the likelihood is very high that he won't ditch her.
Because he knows that she turned her back on what she had been doing.
In spite of the consequences to herself, she turned her back on the path of evil.
He knows this to be true.
Remorse.
Conviction of sins.
Acceptance of punishment.
Now she can be forgiven.
Now she can be redeemed.
(Yes, there are Christian religious overtones in how I phrased all of this, but in this case I feel that the concepts do apply, that this is precisely how one should look at this. Effectively, for Elk, this is being born again, this is the new birth.)
