Would you say one of the reasons Lucas and Maya are distant post-Ski Lodge is because "We're no good at it (being just friends)"?
“We can still be friends, not really.”
MOST people understand that their behavior in S1-2 was not actually the behavior of “just friends.” Most of it was FLIRTING. That’s a big part of the reason they barely interact after SL2. He’s legit got a girlfriend now, and that girlfriend is Maya’s best friend.
Assuming we get an S4, I think we’ll see Rilucas deal with the consequences of how they handled the game changer in terms of their relationship. I think they’ll be in a vague place again for a while and then break up relatively amicably. Then we’ll get the full Farkle/Lucas switcheroo, and you’ll have Lucas (or maybe Zay, or both) being the one who helps Maya deal when Josh perhaps doesn’t “play the long game” by the same rules as Maya, and Farkle slowly becoming more and more Riley’s real love interest. Something like that. Square dance basically.
