The implications of Bridon EP6 are crazy!
Basically for anyone who is confused what transpired during ep 5 and 6, here’s what I understood. Essentially anyone who uses CX’s power to go back in the past is overriding the original timeline. When CX accidentally jumped into the fire in ep5, he called out "Dad!" so his mom noticed him. His mom then tells Wang Qing that if you ever meet him let her know because he has the same power. So when CX meets Wang Qing later on, she takes a picture for CX’s mom to possess her from the future so that she can meet her son in the past. It was because CX went into the fire that Wang Qing even knew to look out for him. That’s wild! So much depends on CX’s unexpected decisions when he goes back in time.
Side note:
I've seen some people ask “Wouldn’t CX meeting his mom in that moment cause ripple effects in the future? Won’t that disrupt the timeline” The crazy thing is no. Because she essentially tells CX not to pursue the issue any further and their conversation occurs in an enclosed space. The only variables are him and his mom so if both parties act like nothing happened, very little ripple effects can occur from her decision to meet him in that room.
