The Violin - S5-E5
Question: All the way up until season 5 Nelly (the nice Grandma) and Martin get along nicely. In season 1 EP 3 they are joking with each other. In season 2 EP 7 he apologises for pouring water on her (and keep in mind he is being sincere here). But in this episode he hears that she had a fall and suggests that she have a bigger one. What happened?
Answer: It's not explained fully, but its shown that he is quite sick as he has been taking many dollops and that they were liquid (sorry for the graphic description but its explained in the show). Given those circumstances we can safely assume that Wilson has got some severe problems.
