The series alternates between letters in two patterns: the first letters (a, g) are separated by 6 letters, and the second letters (f, l) are separated by 6 letters as well. Continuing this pattern, after 'g' (the next letter would be 'm'), and after 'l' (the next letter would be 'r'). Thus, the next two letters in the series are "m" and "r", making the next sequence "m r".

The next two letters in the series "watntlitfs" are "e" and "h," forming the word "watnthlits." The series can be interpreted as a jumbled version of the phrase "want to lit fest."
It's likely that the missing letters are ff. They are the first letters of the counting numbers one, two, three, four, five, six, seven...
