Najm and Alya were pretty solid from the start - the general forms of the Tazdahir uniform (tracksuit with turtleneck) was made pretty out of the gate. Qam and Rahat were later additions and were much more fluid - Rahat got a whole different hairstyle and vibe, neither of them had very solid personalities - the whole plot of STS was very wibbly wobbily in the beginning. It's still a little wibbly around the edges.
