I saw that
Cracking semi.
She accepted it though, although they didn't really need it in the end.
Yes , I did find it was strange that she did though ...
I think she gave it as she knew they understood the relationship and gave an answer, although odd, was still correct if it were a word...if you know what I mean.
I don't know if they've every discussed how they "mark" answers on OC (or if they would ever want to do so publicly) but I think Victoria is allowed some tolerance in what answers she can accept. From previous shows (and from what she said on this one), it sounds like she can accept a "questionable" answer if the team have clearly shown that they've understood the sequence and made a reasonable stab at an answer. In this case, they showed they'd solved the puzzle by adding consecutive "E"s and then forming an anagram - even if the answer they gave was a (dubious) phrase rather than a single word.
I don't know how common it is on other shows, but we know from comments Victoria has made previously on OC that the main question-setter goes over the questions with her at length before each show so that she (sort-of) understands the questions and what other answers are allowed if there are multiple possibilities. I vaguely remember a previous show where she accepted as an answer someone who's given and family names started with "D" (e.g. Dave Dee), instead of what she was expecting, which was a double-act whose names both started with "D", because the team were still following the "AA", "BB", "CC", "DD" sequence, which was the main point of the puzzle.
