The reveal that Russ used to hurt Tyler reverberates through the Brennan clan. Mark is especially in shock, realising that he hasn't been there for his younger brother. When Russ finally apologises to Tyler, he doesn't seem to understand the implications of what he's done and it's not until he receives some very frank words from Sheila that he realises the true damage of his actions.
