Climbing Plot Mountain

Shit. My novel has just handed me another subplot, on page 222 of about 300. At this point I need to be wrapping up subplots, not creating new ones...especially new ones that appear to violate my previously held and defended belief that subplots be wrapped up in the book in which they're created, damn it.

If the chaos that ensues from this one's inclusion causes readers to shout "Authorial Intrusion!", I'm going to scream.
