At this point it's obvious that Golden Cicada and Tripitaka don't get along (or at least Cicada can't stand Tripitaka), not to mention that they both have their own ideals of how Tang should be completed.
How much do they fight about it and how long does Tang put up with their fights? Have they ever attempted a truce for Tang's sake?
Like, a random demon ends up chasing Tang to eat him and Golden Cicada and Tripitaka have to deal with each other to prevent the scholar from dying.
For some reason I can't stop imagining a scene in which Tang is being chased by a demon and Cicada along with Tripi have to advise him on what to do. But suddenly they both start an argument (perhaps because Cicada said something about killing or seriously injuring the attacker, and Tripitaka obviously disagrees and better advises to hide and wait for help), the fight develops from there.
Leaving Tang to his fate, and when Tang manages (in some miraculous way) to get rid of the demon that was chasing him, he returns only to watch as the Golden Cicada and Tripitaka continue to fight without even noticing his presence. So Tang just walks away from them not willing to put up with this and goes straight to Pigsy's shop, while he lets the other two verbally tear each other apart.
Sorry if it doesn't make much sense I'm not going to sleep yet.
