Little surprised about Taylor & Isaiah, given there was evidence they were present at the finish line in California. Wonder what happened. A little clarification at the outset of next leg would be awesome.
As for the other three teams, Connie was 6 months pregnant, Caro & Ray had split up and Spencer had some health issues across 2020/21 so that may have been the reason they could not return.
Strangely enough, I was most invested in the teams that are returning, so I am happy with the seven that will return for leg 4.
