On the night when they was talking to their friend on skype at the kitchen table at one point leora went to show malia something on her phone, as malia pulled her chair closer she gave leora a little kiss on the shoulder which made leora shiver , they then laughed together.
Also one of the reasons might be there has been less physical contact between them is there has been hardly any alcohol in the house since malia got very drunk. And now seem happy too just binge watching tv series.
