It makes absolutely no sense as to why a man planning to kill Trump would drive nonstop from Oklahoma to Columbia county to meet a woman(which according to info we've seen so far, he has never met irl) and who claims to be a supporter of Trump. To make it even more bizarre, the man actually warned the woman she is in danger and opened up about hearing voices in his head which tell him to kill the president and his family, he even pinned it on CIA.

These 2 obviously knew eachothers very well and it wouldn't surprise me if he was a former patient of her. Not really sure what Q meant by "not the person" as in she's not the person who attempted to kill POTUS or we shouldn't be focusing on the person but instead the intelligency agency(CIA) behind it(which was named on that newspaper)
