Lorelai is so disturbed by Mia’s news about selling the Independence that she begins backtracking on her plans to open her own inn, to Sookie’s dismay. Logically, it doesn’t make much sense – if Mia is going to sell, Lorelai and Sookie should be fast-tracking their plans, not shelving them. Mia even said they should make their move sooner rather than later.
A lot of Lorelai’s angst about the Independence being sold is the thought of her home being changed. Her special relationship with Mia would be severed, and the new owners of the inn could very well be faceless corporate types that turn it into a chain (always treated as some sort of ultimate horror on the Gilmore Girls).
For Sookie, who isn’t so emotionally invested in the Independence, the news is positive. Mia won’t be upset about them starting their own inn, and even if the Independence changes, they have their own lives to lead. She’d prefer the inn didn’t lose all its charm, but she’s sensible enough to realise that they can’t control what happens, and to focus on their own plans.
This difference in how they feel is enough for Lorelai to begin passively-aggressively attacking Sookie, and to shoot down any suggestions she has on how to improve things. Sookie wonders why they don’t buy the Independence, and Lorelai says they can’t afford it – even though she never asked Mia what she would sell the inn for.
Sookie asks if they should look for another inn to buy, and Lorelai says she doesn’t have time to look for a new location (because if someone doesn’t just randomly show you an inn, it’s too much hard work? Did either of them even check the real estate guides for the area?).
Finally, Lorelai begins criticising Sookie as a potential business partner. She is unreliable, not punctual, and keeps changing the menu, which would send them broke. Sookie is naturally devastated, but Lorelai’s criticisms seem like valid concerns. Even Sookie doesn’t have any comeback except to say Lorelai already knew all these things before. She doesn’t make any promises to change or improve, or suggest other ways she is going to support Lorelai to offset her flaws. In fact, Sookie’s flakiness is actually a problem when they do become business partners.
Notice that Lorelai tries to back out of their business deal by saying the “timing isn’t good” – the same weak excuse Rory made to Lorelai when she tried to wriggle out of going to Chilton.
