Andy Murray is still haunted by the demons of Tokyo three years ago, when he felt he and doubles partner Joe Salisbury should have come away with a medal.
They looked one of the strongest pairings in Japan and had been a set and a break up against the eventual silver medallists Marin Cilic and Ivan Dodig of Croatia, only to lose 10-7 in the deciding tiebreak.
Murray cut a frustrated and grumpy figure at the time, having missed out on a potential fourth Olympic medal and knowing it could be his last Games for Team GB.
And yet, here he is with Dan Evans, seemingly being given lifeline after lifeline to prolong his career.
Twice the British pair have looked set to exit the tournament, first saving five match points in their opening match and again two more in round two.
In the fourth match today on Suzanne Lenglen court, the close friends will be hoping for an easier, less nervy passage into the semi-finals against Americans Taylor Fritz and Tommy Paul, to put them on the precipice of that fourth Olympic medal three years after coming so close.
"I lost in Tokyo with Joe from a set and a break up, and playing extremely well," recalled Murray after beating Belgian pair Sander Gille and Joran Vliegen. "The way the scoring works in doubles and the way teams play, the margins are so fine now, but we definitely have a chance of making it to the semis."

Aged 37 and 34 respectively, Murray and Evans are no spring chickens, but moved very well throughout their second-round match and, for the first time, hinted a medal might be possible.
And Evans is just relishing every opportunity to play with the two-time Olympic champion.
"Andy's amazing to play with and it's an amazing atmosphere," said Evans. "Everything from the lodge, the village, Team GB, it has been amazing to be a part of, whatever is happening.
"I'm just over the moon that I'm here. Andy is so good under pressure. I didn't think it would be, but it's been emotional."
