Obviously a horrible setup hand for Andy, and he's losing to only two hands -- Td8d and KdTd. Turn and river don't change anything, though the fourth river diamond gives a huge clue when Mariano goes all in on Andy.
Not sure if the call was this quick in real life, or if it's just compressed for time above, so I won't comment on that part. If Andy did call very quickly, that was a mistake. At the very least, he needed to think it over.
I don't under the checking back on the flop on both sides. This is the type of board where you can get action from a lot of hands, so why not pump up the pot right away if you think you're ahead? It's not like you're holding QQ on a QQ4 board, and figure you need to let the other person hit a piece of something. On QdJd9d, there's a lot of hands which can call a flop bet, especially since Andy knows Td could be held by Marino, and Mariano knows that Andy could have Ad.
The lack of action on the flop actually would have given Andy the chance to possibly fold on the river. If there was no fourth diamond, Andy would have to call, because Mariano could simply be overplaying a lesser flush. But with a single diamond making a flush, Andy had to consider the strong possibility that he was being raised by a straight flush.
I definitely would have considered laying this one down. Could I actually do so in a real-world setting? Maybe. It would hurt tremendously to lay it down and be wrong here, but sometimes you just have to reason it out. Very tough to do, though.
