Now, Reg is entering the garden. Since Tom is around, Norman probably figures that there's no point in hiding yet again. It seems that Reg is rather surprised to see Norman. Tom on the other hand...

There are no surprise there. Tom gives his salutations, and then walks into the house.

Once Tom is gone, then Norman proudly reveals to Reg that he's having a little side fling. They both get a good chuckle about it. However, all of that has to stop as Sara enters into the garden from the dining room.
