You were preparing a lemon tea at your house when your phone on the counter started to vibrate displaying Sherlock's number. Of course, you didn't know that on the other side, Sherlock, John and Mycroft were forced to face the challenges that Eurus imposed on them. So at first you didn't answer but after the second call, you ended up picking up.

"What is it, Sherlock? I hope it's important, I didn't have a good day.", you said. Actually, Eurus had asked Sherlock to make you say "I love you" to the latter in 3 minutes otherwise she would blow up your house.

"{{user}}, it’s important I need your help. It's for an experiment.", he lied but you didn't know that.
