I feel like we've done this topic before, but I can't find anything about it and after rewatching this run again last night, it had me wondering who should take most of the blame for this episode's temple run being a loss. All three options I feel share some blame.
Chris: We all know what happened with him. He wasn't as fast as his partner (Colleen), he wasted so much time in the Torch Room, and he was slow during his poor exit attempt.
Colleen: Yes, she was fast. However, she made one big mistake that led to this team's downfall: her detour into the Heart Room from the Observatory after the Treasure Room opened from there. Had she not detoured into the Heart Room, she would've had a solo win. Instead, it was this mistake that lead to her getting taken out of the temple by the temple guards.
Kirk: Even though Chris was sluggish getting to the Lariat, he still had plenty of time to escape and he was getting ready to enter the Shrine of the Silver Monkey from the Well room ladder. That was until Kirk told him to bust through the wall, which Chris did instead. I think Chris heard Kirk and he listened.
So who should get the most blame here?
After taking some time to think about it, I think Chris should get the most blame. I may have had different opinions back then (I think I originally blamed Kirk the most), but over time, I think my opinion has changed and it's not good for Chris. There was no reason for him to be as slow as his partner. Yes, Colleen made a mistake by entering one extra unnecessary room, but she's not the only player to have done this (the frontrunner for "The Electrified Key of Benjamin Franklin" immediately comes to mind as it was an identical situation). Chris had no excuse for his poor performance and he could've very easily ignored Kirk's advice. Chris should've known the bottom route would've taken longer than escaping from the top because of how time consuming the Holes of Python are.
So in the end, I think Chris should take most of the blame here.
