who passed away towards the start of season 4<\/a>.<\/p>\nAt his funeral, older brother Ewan (James Cromwell) gives a speech that offers a relatively fair assessment of Logan\u2019s life and character, as well as lifting the lid on his most guarded family secret.<\/p>\n
He explains that, after being evacuated from Scotland to Canada during the Second World War, Logan attended a boarding school for a short time and strongly disliked the experience.<\/p>
After much complaining, he was eventually sent home, unaware of the fact that he was carrying poliovirus. It wasn\u2019t long before his sister came down with a fatal case of the illness.<\/p>\n
While there is no way of knowing if Rose caught polio from her brother or from somewhere else entirely, Logan always believed that her death was his fault \u2013 something that his abusive uncle Noah drilled into him regularly.<\/p>\n
Indeed, the cruel treatment that Logan received as a child from his Canadian guardians is considered by some to be what shaped him into such a cold-hearted man, with Rose\u2019s death being a previously unknown tool of torment.<\/p>\n
The Roy children showed themselves to have some knowledge of what happened to Rose in season 2, when they tell rival Rhea Jarrell (Holly Hunter) to mention her name in a toast to Logan. To say it strikes a nerve is an understatement.<\/p>\n
The revelation is one of several memorable moments in a dramatic funeral, which also saw Roman break down in hysteria and ultimately seek out harm in the crowds of an angry protest.<\/p>
