Fantastic as usual. I like the fact that we're meeting the source of Frank's issues. What I miss, however, is seeing the other four boys regularly. I definitely think you should bring them back in at least for a small cameo.
Another note, that was not long at all. x) In fact, (please note that I already enjoy this story immensely) if it were longer I'd probably enjoy it that much more. x)
As usual, good writing on your part. You're one of the few authors around that can keep me interested for this long.
Can't wait for the next chapter.
