Raphael felt Michael's arm but he didn't respond. Instead, he sat as still as stonge, impatient for everybody to leave. He wanted to bolt but he didn't plan on doing that in front of Adam. As for Michael, he didn't dare look at him - the weight of the situation frightened him and seeing Michael only made it worse in some ways.

So he said nothing and did nothing except wait for the chance to go off and be alone.
