You see, at age 14, the Wellington College pupil rather thought he'd be back at Twickenham in the lily-white of dear old England. Even if such a prospect did turn his Scottish grandad puce with rage.
Max, who qualifies for Scotland through paternal grandfather Fred Thom, will not be short of patriotic passion this afternoon - even though he freely admits; "When I was young, I supported England; I supported South Africa because my mum was South African and I supported Scotland because of my grandad.
"But it was funny because, when it came to Scotland against England, I supported Scotland. I wouldn't dare be a neutral in front of my grandad.
"Now, coming to play England, I've grown up with the influence of my grandad so there is no lack of enthusiasm to go and beat the hell out of them.
"I've actually played at Twickenham before, but obviously not in the big atmosphere. I played a few times, first in the Daily Mail Cup, then the Middlesex Sevens and the London Sevens two or three years ago.
"When I was playing there at 14, I kind of expected to be back. I wanted to play rugby professionally almost from when I started playing the game. But it's funny, because back then I was eligible to play for England, I went through the England schools set-up as well, so I was actually thinking of making it back there playing for England.
"I played schoolboy rugby with James Haskell, who was in my brother Thom's year at school, so I'm really looking forward to roughing him up this weeknd.
"I might need earplugs, though, because he's got a bit of a mouth. I'll just try to get him sent off again, like he has been in most of the Six Nations!
"It is a strange thing that Thom was actually inches away from being tied into England. But he's had exactly the same experience as me, always at our grandparents' home on our little breaks, so he feels the same. He has just come that little bit closer to almost playng for them than me.
"I've been sharing with Thom this week and we just have to mention it slightly, just a look, to know that we're both really up for it.
"Because we've got mates in England its extra. So, we've got the likes of Haskell plus a lot of our mates who, while not involved in big-time rugby, will be supporting England. It will be a good feeling to beat them and have the bragging rights."
Both Evans boys display commendable optimism but, on this occasion you can't help but feel that their high spirits are misplaced. After all, winning Scotland teams at Twickenham are rare.
Not even the weight of history can crush Max's spirit, though, as he continues to adapt to his first taste of the Six Nations - a campaign that has earned personal plaudits amid the horrible run of results.
"I'm very excited about this weekend, almost more excited on the back of how the Six Nations has gone so far," said Max. "I'm just so up for getting a win this time, instead of just a near-win and losing it at the end, because this has been my first Six Nations.
"OK, we've been losing, and I hate losing. It's a horrible feelingfor a few days afterwards - you take it right up untilt he next game. But because it's a new thing, I've been enjoying it at the same time. When you do something you love and it's all new, you have to enjoy it.
"So, there are mixed feelings. I'm starting to get fed up with losing already.
"I love having space and that's something you really don't get that often in international rugby. I got a little bit of space in the Italy game, but it was more counter-attack, off a kick, but it really doesn't come that often.
"I've tried to work hard on posing a threat. In the Ireland game I didn't get much ball but, with the ball I did get, I tried to really have a go, especially at Brian O'Driscoll.
"That's something I'm going to take even more into the England game. You're not going to beat players the first time you get the ball - it's all about getting over the gain line with the little space you have.
"That's what helps the team. That's something I've personally noticed and I am really looking forward to improving."
