Keeping your opinions to yourself=/=being two faced or fake. At least to me, two-faced/fake is somebody who'll be nice to someone else and then awful behind their back, think Caroline about Becky. He just doesn't feel the need to throw his opinions out to anybody with ears (in the house at least). Although I get the feeling that even if he did feel the need to voice an opinion, he'd be cautious about it. Call him cowardly and I can maybe see where you're coming from, but fake and two-faced are a reach.
