This!! Seems to be the most plausible if we consider Q's post about a special place for GS. Timing seems relevant. Up until this point everyone has left out the [. Seems natural to have both brackets. Good job anon!
Q could have said bottom of the 9th, 3rd period, 7th inning stretch or any number of things relating to sports. Just a day or two before he hinted us to look at the context of his posts and POTUS tweets and both referred to the Army/Navy football game. Q specifically said "4th quarter, Patriots.". There are no coincidences. Stop dismissing this possibility.
