Love the post… but the first part I quoted did confuse me a little. 
… he didn’t call. He sent a text to a friend. 
he was standing in the doorway between the rooms. Helen was in Tommy’s room and Dave in his and Helena room. So. Technically Tommy can hear all that’s being said. But I guess we will say he went toward the bathroom in his room.
Why does he even care. He was spending time with Ravi and kissing her. lol
