Johnston cut it to 3-2 with a short-handed goal at 5:04 off Theodore’s giveaway.
Johnston’s second goal of the game then tied it 3-3 at 11:54 of the third period.
“It's huge. It always seems like the games with these guys are kind of whoever's up, whoever scores first ends up winning,” Johnston said. “So, it's great to get that comeback win.”
Dallas defenseman Miro Heiskanen left the game at 7:56 of the third and did not return after Stone collided headfirst into his left leg.
“I just talked to him, we'll see,” Stars coach Pete DeBoer said. “I've coached Mark Stone. He's not a dirty player. He's not trying to hurt anybody. … Just pray that we'll get some pictures, and we'll see.”
NOTES: Johnston became one of eight players in NHL history to complete a natural hat trick in overtime. The only other active players to do so are Evander Kane (Nov. 15, 2023; Edmonton Oilers), Kirill Kaprizov (Feb. 26, 2023; Minnesota Wild) and Hertl (Jan. 8, 2022; San Jose Sharks). Johnston (21 years, 259 days) is the youngest to accomplish the feat. … Hertl became the second player in Golden Knights history to record a point streak of 10 games. Eichel (12 games in 2023-24) is the only other. … Stone (two assists) became the fourth player in franchise history with 200 assists, joining Theodore (261), William Karlsson (226) and Jonathan Marchessault (225).
