Caitlin is a smart and intuitive cookie.

Likely train of thought:

1. There are 2 common contractions that are 3 letters long with 2 letters after the apostrophe: I'll and I've.

2. I'm going to pick L on the hunch that the first word is "I'll" for an easy 2 letters and potentially more in the rest of the puzzle.

3. Only 1 L showed up, implying the first word is I've.

4. The single letter (third word) is "a" since "I've _ _ _ I" will never[citation needed] make sense. The second word must be a verb of some kind since the first is a contraction of "I have," and "I have the a..." doesn't fit, nor does "I have" plus any noun (like "I have cat a...") will also not make sense. So word #2 must be a 3-letter verb of some kind.

5. "I've got a lovely bunch of coconuts" doesn't fit. Haha.

Maybe she just had a good feeling about the answer?

You risk Bankruptcy with each spin. This is wise only if the prize is the pair of ceramic dalmatians ($800)

Or someone could be feeding her the answers.

In Bill Carter's imminently readable Night Shift, Pat Sajak was called "the most unambitious man in show business" for, among other things, consistently "phoning in" his performances during his failed late night show in the 90s. The exploits of Leno agent Helen Kushnik alone make this book a must-read.
