I think foggy and Karen stayed seperate cause it wasnt obvious why they were involved. Jessica and Luke are known and Collen is besties with Claire. So how all those characters are lumped together makes sense. Foggy and Karen need to protect Matts Secret. Luke/Jess are already way out and like the joke later in the series danny tells anyone who will listein hes the immortal Ironfist.
Them being more secretive nd keeping to themselves is what i took from it. No idea if that was the intention though, just my 2cents.
