Yeah, there was an episode in Matt Smith's first season where he was hopping around non-linearly, but I don't think he actually interacted with himself at any point.
Pierce was Winnipeg's QB during the dark ages (2010-2013), but has been a very vocal fan of Winnipeg as a city, and has been on the coaching staff since he retired as a player in 2014. He seems like a really good dude.
BC is the only other team in the CFL he ever played for - he was with them prior to his time with Winnipeg, and again briefly during his last year before retirement.
Why did the Bombers get rid of him in the office?
On or around Grey Cup Sunday (I can't remember exactly which, but I don't think it had anything to do with the outcome of the game), they said on TSN that Pierce was being granted the opportunity to speak with other clubs about an HC position. It sounds like it was pretty amicable - everyone knows that upward mobility is a challenge in the league.
I wonder if "senior science officer" isn't actually a very prominent position - by this era of Starfleet, the Operations officer tends to fill this role.
I think the TNG Technical Manual explains that the Ops officer manages and allocates the ship's resources like sensors, while the actual scientists are presumably down in their labs rather than on the bridge.
If that's still the case, I wonder what a science officer on the bridge actually does.
I'm guessing he still would have been compelled to sing...but the content of his song may have been different, as he would have had different things on his mind at the time.
Maybe a number about gaseous anomalies.
