Whose friendship do you think was more tenuous and whose do you think was the strongest ?

We see that the women were quite close as a group but we’ve also seen them fight among themselves. Including the peripheral women (Mary Alice, Katherine, Renee, Edie) which dual friendship do you think was the strongest and which do you think was the weakest ?

I have trouble thinking of a really strong bond for each of the women. On top of my head I think Bree and Renee COULD develop a strong friendship but it wasn’t shown.
