Neither naught or WCT were friends with bella, bella was in her own little white knight group controlling chris. WCT tried to be friendly with her so he could keep a short leash on her, bella was very defensive about it. WCT said naught actively tried to push bella away which might be why bella was defensive about WCT trying to interact with her, but that's just from what WCT said, I didn't witness anything the Watchmen ever did myself.
both naught and WCT knew bella was a ween but they couldn't get chris to not interact with her, or the praetor crew in general for that matter. naught tried to outright demonize them while WCT tried to pretend to be friendly with them to facilitate open communication so they could know exactly what praetor was planning next. Neither plan worked, but, it's Chris, what can you do.
