We saw Jamie sinking to the botton of the water in his plate armour. He and Bron dived into the water right next to Danerys. Now suddenly they are at the surface and miles away from the point where they dived into the water. This is not what we saw happen at the end of the last episode. There is no way that Bron would have been able to haul jamie through miles of water with that plate on, and why would Danarys just let them get away? Complete trash writing.

The writers are taking the pi ss

It's like minutes after they're back home. Not surprised as this season it's like Los Angeles - it just takes them 20 minutes to get anywhere. Disappointing though that Dany didn't capture them (imagine a Bronn/Davos/Missandei convo) but glad Jamie had a moment with Tyrion, not enough but better than nothing.

There was a famous line on SIMPSONS that if you can't explain something in a fantasy, throw in magic. So maybe Jaime as a prince and military leader, has magic armor that doesn't weigh anything (lol).

Not if you're using the SIMPSONS style cop-out.
