The second part is an endurance/puzzle type thing, the type of thing Memphis and Dan have thrived in and Jerry has walked in. Dick and Danielle had to dive in the swimming tank for that, I doubt Jerry will be top notch for that one, either.
I just hate how everyone is acting like Dan and Memphis are the first one to say Jerry will be a walkover when practically everyone said they could beat Jerry in endurance(this, including Keesha). Jerry has come last in most of these things and the second part type of competition he has walked in it. That's at least a 50% better chance than Keesha.
I get that there's a bunch of mad Keesha fans that she's going home and they are trying to reason with it by saying it's a bad move to justify her leaving or something, but when you look at it it's really not. Keesha outperforms Jerry in these competitions most of the time, and if Dan and Memphis think they have a better chance at Jerry let's see how it turns out, if they're wrong, scold them all you want for the decision. But in my eyes they have a much broader chance at winning with Jerry there.
