Two things I noted after watching the video of Trudeau leaving his seat. The first was he seemed upset that the vote wasn't going forward, and did walk with a purpose into the middle of the MPs to drag Brown through. As they say in the military, Trudeau was walking with a purpose. I think that he was ticked.
The other thing which hasn't been talked about is his second trip across the floor. It was directly through the MPs. He was going to talk with Brosseau. Probably to offer an apology. Okay. Why did he not walk around the other side of the table? Our left, his right. No one was there to block him. The manner in which he walked and the route he took suggest to me that he was ticked and was aggressive stride.
Not very statesmanlike. If you want to be the PM, please act like one.
Trudeau's second trip across the floor can be seen at approx. 1:20 You will note that he purposely moves through the MPs, rather than going around the other side of the table where no one was standing.
