This may be difficult for some here to get their head round but some people do not go around picking fights simply because they don't like someone. I don't really see that Marcus is doing much more than simply not picking fights and not get involved in pointless arguments.

As much as people might want him to, Marcus does not generally allow his behaviour to be dictated by grudges and perceived slights. As IsleOfWeather pointed out, each day is a new day for him.

Of course, we have all seen what happens when someone starts on Marcus or he does get involved in an argument: he's full on.
