#2 Friend: William Regal
If you were not aware, Triple H and William Regal have been great friends for many years now - stemming all the way to their days as a tag team in WCW.
Whenever Hunter's needed someone to talk to during a tough period in life (especially during his multiple injuries), William Regal has always been that guy (and vice versa).

Though William Regal has had some issues related to drug and alcohol usage in the past, WWE have thankfully looked past his previous problems with the input from his close buddy, Triple H.
Now working alongside Hunter down in NXT, the two spend hours working amongst each other making their weekly shows as impactful and awesome as possible. As long as Triple H holds some power in WWE, William Regal will be right alongside him - much like how Michael Hayes and Kevin Dunn are for Vince McMahon.
