The youngest member of the Holmes family is unique and assembles a very different type of personality among Sherlock and Mycroft. She taught the violin to Sherlock and In season 4 she also played the role of therapist for John Watson. 

As Mycroft said, Eurus appeared to be able to observe truth beyond both the normal scope and even his own. In her childhood, how Eurus together once commented on how funny her older brother looked like an adult 

In Season 4, As Mycroft gave her a Christmas treat as interaction with Moriarty. We figured out she has the capability of reprogramming others and thus compromising, as shown in her former psychiatrist killing his family and himself. 

In her childhood, Eurus displays the signs of isolation, after she burnt Musgrave, she was sent to the maximum-security psychiatric prison, Sherrinford. At the end of the Season, Sherlock found that Mycroft knew where her sister was. He met her sister in Sherrinford Prison where he got to know so many things that he forgot.

News about Sherlock Season 5

In an interview, Martin Freeman said to Collider, “Benedict Cumberbatch, Mark Gatiss, and Steven Moffat are super busy and that’s the reason they do not want to run the risk of ruining the show’s legacy by producing a subpar season.

From this, you can take an idea of how right we are. Also, Martin said that there could be a Sherlock movie instead of Season 5. As he said, “Yeah, I think it is possible. It might be more likely, yeah. I think we’ve all left it so that it’s not a full stop, it’s just a big ellipsis or a big pause. Maybe it’s because we don’t want to say, ‘Oh, it’s a full stop.’ I’m not sure. To be honest, I’m a big believer in not going past your sell-by date, in anything. Don’t outstay your welcome.
