Sherlock Season 4: 9 Big Questions After 'The Lying Detective'
2. What Does Euros Want From Sherlock?
Eurus has came back into the life of Sherlock after who knows how many years away (or is entering it for the first time), tricked him and his best friend, and pointed a gun at the latter.
It's not something you do without a purpose, which begs the question of what exactly Eurus wants from Sherlock. Given we know very little about her, it's hard to discern what her motives might actually be.
Is she trying to hurt him, or perhaps get to Mycroft on a revenge mission? Maybe she really needs his help (but is going a very weird way about it)? Or could she be working for someone else?
