Tkachuk, like his skipper, is a firm believer in the do-as-I-do philosophy, not the do-as-I-say. Night after night he's out there, playing on the tightrope without a net or parasol, only the collective welfare on his mind.
"There's still a time and a place, though, to speak up," he reckons. "But you have to know the right moment to say the right thing.
"When nobody wants to say anything, when everybody's staring at their skates in their stalls and the room is so quiet, that's when you've kinda got to step up and be heard.
"If guys are down after a tough loss, maybe then.
"When we're not playing up to our potential, maybe then.
"But it's all about the timing."
Saturday is the Flames home-opener at the Scotiabank Saddledome, Tkachuk and the rest of his brethren determined to wash away the bitter taste of a 5-2 curtain-raising loss to the same Vancouver Canucks on Wednesday.
"We've got to be better,'' he says. "And that starts with me."
The evolution of Tkachuk, his growing influence on the present and future of this team, will be one of the most compelling storylines moving forward.
Asked if he's set any targets to chase over the next six months, the newly-appointed alternate captain replies with a firm head shake.
"I'm not,'' is the frank confession, "a big personal numbers guy. I'm not someone to sit down before a season and say: 'Oh, I expect to do this' or 'I should be scoring that many goals'.
"What I do want to do is continue to make myself a bigger part of this team. That's a goal. For sure.
"I don't want to take any nights off this season. I know there have been nights over the past couple where I haven't started great and failed to make an impact during a game.
"I want to eliminate those.
"Most of all, I want to help this be a playoff team. For a long, long time.
"Starting with this year."
