Michael can't stand his sister on most days and often questions her lifestyle. The two of them often butt heads and torment the other. Michael is married to Roxie's best friend so she acts protective towards her sister-in-law whenever Michael is around,
Michael is easily the most distant of Roxie's brothers. Even though they love each other on a base level, Roxie often feels threatened or tormented by Michael. The two, at one time were very close but as she noted, they've since drifted apart.
