Daniel helplessly shook his head and thought, 'I am not going to let these two men make me stay away from my woman. I am going to Rachel by hook or by crook'

Daniel drove towards Rachel's home but parked his car at a safe place a few meters away from her house. 

From there he carefully walked to her place.

He then headed to the backside of her home and came across the security guards.

After the attack on Rachel in Italy, and finding out Frank's involvement in it, Daniel and Harry recruited the D-Team of their secret organization.

D-Team is one of the best teams they have but they are not the top ones and neither they are the worst, they were perfect to act as Rachel's security.

This D-Team flew down to London and since then they  have been taking care of her.

Now, D-Team was responsible to take care of William and Liz too.
