It seems Granger is engaged in a rather heated conversation with Thomas. Their faces are mere inches apart and their expressions at least give an idea of the nasty words they are hurling at each other. We can't hear them because they're too far away and also too quiet, but the furious glint in Granger's eyes tells me that it won't be long until she explodes. Thomas looks similarly angry. His face is scarlet red and his teeth are bared.
