Triple H’s role at Summerslam

Hey so last Monday they officially announced Cena vs Lesnar.  Now early reports rumored that Triple H would face Roman Reigns at Summerslam, however the ending to last Monday's RAW almost suggested that it would be Randy Orton facing Roman Reigns.  Now they could do Orton vs Kane and still do the rumored match but if they don't my question to you is:  When does Triple H insert himself into the Cena/Lesnar match as the special guest referee?  Triple H making himself special referee at Summerslam is almost a tradition now.

​Well, the logical progression is Reigns going over Orton at Summerslam and then moving onto the REAL feud with HHH at Night of Champions, unless they really want to stretch it out by doing s--- finish at Summerslam / s--- finish at NOC / Hell in the Cell at the PPV of the same name, and then move onto HHH at Survivor Series.  Either way, the Orton -> HHH progression seems to make the most sense.  And then HHH can make his life hell until he wins the Rumble to get revenge and yada yada millions of dollars made etc.  ​
