From the pics, I think the Afghanimals were u-turned. (1) The 1st u-turn slot was already taken when they got there, (2) Jamal said, "We have to u-turn someone," (3) Jamal was wearing the dance outfit from the dance detour, (4) Leo said, "We might be in last place right now," (5) and if I'm not mistaken,
there was a spoiler pic showing that they were performing the statue detour.
I'm just wondering who u-turned them.
And also, pic 21 is not long beards, I think it might be Oklahoma, I'm just not sure though.
My theory: Someone u-turned Afghanimals, then Afghanimals u-turned Oklahoma (maybe because Afghanimals were sure Oklahoma were behind)
