I'll give you Lola and Lana have had an episode where they are the focus (Patching Things Up), but in regards to Lynn and Lucy or Lori and Leni there haven't been any episodes where they are solely the main focus. While Space Invader did involve Lynn and Lucy it was more about Lincoln having to deal with Lynn being his roommate, Lucy's main contribution only came towards the end of the episode. While Brawl in the Family did involve Lori and Leni it was more about Lincoln either trying to stop their fight (while making it worse in the process) or having to deal with the SFP, they where a B plot in Vantastic Voyage, and Fandom Pains was about Lucy trying to get them to stop watching her show.
