Does anyone think Katie should stay on guard when it comes to Brooke and Bill?

I think so. Even though Brooke is with tired old ridge, she has no problem making out with dollar bill if the opportunity arises. Remember when she and bill made out at hope's cabin that was caught on video by shauna? If brooke were to ever leave ridge for good, you can best believe bill won't be far behind. I hate to see katie get hurt like that again.
