(Note: There's a common numbering confusion. The actual S02E07 is "James Rolf High School Twentieth Reunion" — the company picnic episode is S02E06. Let me clarify.)

The team caters a 20-year high school reunion. Henry faces his ex-girlfriend (and now successful TV actress) Danielle, played by Kristen Bell . Roman tries to impress former classmates with his failed sci-fi novel. Kyle tries to pick up women, and Ron has a breakdown over his ex-wife. Lydia (Megan Mullally) brings her daughter Escapade, who gets drunk.

If you were specifically looking for a (file specs, release group, CRC, etc.), that information is mostly preserved in NFO files from 2010 (e.g., releases by DIMENSION or LOL). Those can be found via scene databases like srrDB or predb.me .
