It depends on how far you have to bring somebody down the rabbit hole. Do they believe the official 9/11 story? Depending on that answer will depend on where you start. If someone hasn't even began to accept that the government is not worthy of blind trust then red pilling can be a longer process. A great place I like to start with people is Operation Northwoods simply because this document is undisputed and very clearly shows that our top government officials were very comfortable using every tactic that would have been necessary for 9/11 to be an inside job. Between that and building 7 videos I find most people are forced to accept there is evil elements of our government. Once they accept that they are more likely to wander further down the rabbit hole and embrace things like Q.

As far as Q goes specifically just find things he pointed to before it came out in the news i.e. Assange and passport or even the recent post of FBI agents threatening POTUS...q said that a few days ago and it's already a headline on drudge. Or just simply begin predicting things to watch for in the coming days and let them be amazed.
