And for that matter why did Todd attend the industry wedding?

Some of our greatest memories/dying hallucinations come from our mistakes. Bojack not only fucked up the Guten Burbon opportunity PC worked hard for him to get around his depression, but his fuckup made Todd the face of Guten Burbon.

I’m not sure if Bojack realized how he fucked his friend over (again) by replacing the prop Burbon with real Burbon but after his genuine disappointment with himself destroying Todd’s Rock Opera it may have become another core memory fuckup Bojack played to himself, adding Todd to the ‘industry list’ under Todd’s Manager PC where he belonged.

It’s an industry wedding but Judah didn’t attend

I’d save the first view of the bride for the actual ceremony myself, particularly as viewing the bride in advance is bad luck for a groom. Or maybe Bojack, who never had a relationship with Judah, was processing and professing his feelings to PC and excluded him out of unfamiliarity/his mind wanting uninterrupted closure with PC.
