Imo, Oswald may have had a Dr.Pepper in hand BEFORE he came up to the 2nd floor, which would be not later than probably 12:12 given Carolyn Arnolds observation of Oswald actually SITTING in the 2nd floor lunchroom at 12:15 earliest to 12:20 latest. Yet, neither Stanton, nor Arnold apparently saw each other.
the late date Stanton relative recalling the story of a "Pepsi". That is rather close to "Pepper". Not coke, but "pepsi"? . Maybe its just a coincidence, idk.
And it would have been very easy for Sarah to have distinguished between a 1963 coke bottle and a 1963 Dr.Pepper bottle due the large solid white label of Dr.Pepper at lower 1/3rd part of the bottle, so not that implausible that Sarah might have actually stated the specific name. Nor that a relative many years later might misremember Dr.Pepper as "pepsi"
So this would change the hypothetical sequence to:
Oswald went to the Dr.Pepper machine on the 1st floor by rear stairs, got the Dr.Pepper, then went up to eat his lunch ALONE in the 2nd floor lunchroom, hoping that all the office woman had already left. This eating in the lunchroom alone, is alluded to by Billy Lovelady in an FBI statement refering to Oswald doing just that.
This may be why Stanton may have told the story to the relative as having seen Oswald just standing around in the area as opposed to having stated seeing Oswald go in or come out of, the lunchroom with the "pepsi" in hand.
At some point Oswald must have gone back down to the Domino room, having decided not to stay in the lunchroom after Carolyn Arnold saw him there. This is about the only way that Oswald could reasonably have probable view and also heard, James Jarman and Harold Norman returning to TSBD back door around 12:23.
That would be when Oswald likely would have left the Domino room and head towards the front lobby, reaching there around 12:24 or 12:25. That coincides with another Carolyn Arnold FBI statement of having seen Oswald at 12:25 on the 1st floor, as she "looked back". That FBI statement, Arnold actually signed her name.
Add in the 2 new 'notes" revealing "out front with Shelly" and "went out to watch P.Parade, and then Dr.Pepper bottle found, in the very recessed step, the one step down, that Prayerblob is located, and with some object raised to mouth with large white spot, on the West side of landing...it SURE IS AMAZINGLY coincidental.
