Epilogue:
After Q's departure, Picard and the rest of the crew got the low down from Barclay. The only comment afterwards came from Geordi who was just happy they both benefited. Q learned and Barclay found out that being a sniveling whelp wasn't very helpful.
And when Barclay finally got to return to his quarters, he found a green leather bound book waiting for him. On the front, in gold embossed letters read 'Journal'. On the inside cover in a flowing handwritten font was, 'Because, in your immense stupidity, you had to go and rip up your diary, Q.' All Barclay could do was smile; after all, Q wasn't nearly as bad as people said he was.
