Friendly reminder that no matter what some distracted interviewers/viewers/antis might say, JB was NOT a one-night-stand. It is literally, physically, impossible to see it as such even just by tracking the number of days that pass in show between their first time and the night Jaime leaves, not to mention listening to the conversations.
Even if you assume that D&D have no regard whatsoever for how long it takes to travel between places, and that the only time that passes is the time we physically see on screen while Jaime is still in Winterfell, that already covers several days: Jaime and Brienne sleep together the night of the feast, then there is a war meeting at daytime at an undefined later point, then Jaime and Tyrion are drinking at an inn at nighttime, then Dany and co. have left and are attacked at daytime at an undefined later point, then news arrives to Sansa at daytime, which would at the very least be on the following day, then it’s night again when Jaime leaves.
All along, Jaime is living with Brienne and the fact that they’re sleeping together is common knowledge, at the very least for Sansa and Tyrion. The conversation with Tyrion is the one that gives it away more than anything else because they are discussing Jaime staying in Winterfell with Brienne and how happy Tyrion is to see him happy and that he has to climb for it. That dialogue is not a conversation about a failed one-night-stand. That’s a conversation about a new relationship that continued to include a sexual component.
The night Jaime leaves, he’s sitting in their chambers with Brienne naked in bed. If their first time had been a one-off, never to be spoken of again, he wouldn’t just be chilling in her room while she’s asleep, naked, in her bed. And Brienne wouldn’t turn to his side of the bed when she wakes up, expecting to find him there.
Yes, everything was so rushed it hardly made any sense, time-wise, but even if you assume that there are no off-screen days whatsoever because D&D “kind of forgot” it takes time for people to travel places and for things (especially huge things like battles, attacks and parlays) to happen, what we saw on screen does not depict a one night stand. JB’s relationship might have been cut too short, too soon, but it wasn’t a hit-it-and-quit it scenario.
