I could tell she was having a rough start with how nervously she was looking at the cards and the monitor off-camera that shows who buzzes in on the Toss-Ups, and when she said "The category is 'Crossword'..." before the first round. Some "um's" and awkward pauses here and there, but she was wonderful. I just smiled the whole time seeing her standing next to the contestants. Minnie seemed unnecessary if she wasn't actually going to touch the letters.
What I found interesting was that all the Toss-Ups began with the last letter even if it wasn't the rightmost letter. For example, the puzzle SOUTHEAST ASIA, normally, the first letter revealed would be the last T, but in this case, it was the last A in ASIA. I remember an episode recently where Vanna was touching the "wrong" monitor and the puzzle wouldn't start, so I always thought Toss-Ups absolutely had to start from the far right.
The best part of her first episode by far was when she thought she landed on Bankrupt for the Final Spin because she was looking at the yellow player's podium (whereas the Final Spin is always decided in front of the red podium), then reached down to spin again before the producers started yelling from offstage and she said, "How do you do this show?" I'm so glad they didn't edit that out.
