She turns back to Gabriel and gives him a look that says "Please, let me handle this."  Only it was not quite a request in her eyes.  She raises a hand to his chest to calm him.  She smiles back to Luke, her hand extended to him.  "You may have to forgive him.  It has been a rather rough week for him."  She lets the understatement stand as Luke was there to see the death of his brother and is aware of the finding out about wiped memories.  He will appreciate the depth of the situation.
