Four. Back to reality from my two yesterday. (Actually I think any time one gets a two it is mostly luck either with one's opening word or the second word. For me, I was extremely lucky on my second word yesterday given the number of letters that could have gone in the fourth position.) Today, I only had one letter after two entries plus the knowledge about what the only vowel had to be. That made it difficult to come up with words for lines three and four.
