Just proceed with the story line. She may be gone after you complete Maxos temple (which can wait until you've done the rest of Broken Valley, or at least gotten up to level 14 or 15), or otherwise leave the main map area and then return. If not, you don't meet her again for quite awhile, and I can't see a glitch here making a difference by then.
If you have the Developer's Cut version of the game (see
here if not), you can use the Developer Mode cheat window to reset an NPC's status. That might get rid of Rhode.
