I think it was a decent decision by him to take out Sindy first. She didn't actually take part in the comps so it'd be difficult for her to remember the names and everything. Also, everyone said she was going to be the target this week so he didn't show where his head is at and just went with what people wanted last week. They still had the numbers in the competition despite that.
He clearly didn't want to get that one right, though.
