Who saw this coming?
A sterling performance by the goalie making his first start for the Golden Knights, against his former team, after being claimed off waivers from the opponent weeks ago.
Two goals from players called up from the AHL over the weekend - their first NHL goals, to boot.
Vegas' 3-1 win over Boston was full of surprises.
Here are three immediate takeaways.
1. Malcolm In The Middle
Who saw this coming?
When Marc-Andre Fleury was placed on injured reserve on Sunday morning, Malcolm Subban was tabbed as Vegas' starter. He of only two career games, and zero wins.
He who's spent most of his pro career in the minor league system of the Bruins, Sunday's opponent.

He who was placed on waivers earlier this month by Boston, and claimed by Vegas.
He who not much was expected of.
Subban, however, was the star of the show on Sunday. He finished with 20 saves on 21 shots, holding a shutout until the game's final minute.
Subban's victory was his first in the NHL.
2. First NHL goals all around
Both Vadim Shipachyov and Alex Tuch were recalled from the Chicago Wolves since Friday's game against Detroit.
Both responded in a big way against the Bruins.
Tuch, a rookie who coincidentally played his college hockey for Boston College, walked down the right-wing boards and picked the upper corner over Bruins goalie Tuukka Rask.

Shipachyov, a 30-year-old Russian who has starred in his native country for the last decade, making it 2-0 Vegas…assisted by Tuch.

When Erik Haula and Jonathan Marchessault - who both scored on Friday vs. Detroit - were placed on injured reserve, some questioned how the Golden Knights' offense would respond. Well, it responded by getting goals from both new players who stepped into the lineup.
3. Mental toughness
It's often said that you don't really learn what a hockey team is about until it faces adversity. Granted, a loss in October might not necessarily qualify as adversity. But Friday's loss to the Detroit Red Wings was the first time the Golden Knights had a setback.
And Vegas responded with one of its best games in the early going, only surrendering 21 shots. Which as good as Subban was in goal, made this as much of a team shutout as anything else.
At 4-1-0, the Golden Knights are off to a better start than anyone could have imagined. Vegas is next in action when the Buffalo Sabres visit T-Mobile Arena on Tuesday night.
