If there was any challenge the designers had to bring it, it is this one. Meg knocked her camera challenges out of the park per usual. Karl is coming into his own on the camera challenges. I loved the comment about not wanting to roll out of the loft bed and into the sink. Mark sealed his fate with his trip up on the first camera challenge although his second was as personable as we know him to be.
Side note: was there an unofficial requirement for the designers to hang animal antlers in their houses? I think all three of them had them. For some reason, Karl and Mark’s antler art reminds me of a Jackelope. 
Jackelops are real because they are on the Internet. Look it up.
