The HHN Icons were heavily featured in the Tribute Store as part of the HHN Lite event last year at Universal Orlando. Jack and company were said to have had a Icons house and possibly a stage show of some kind planned for last year's canceled event and today (June 15th) a leaked commercial / announcement pretty much confirms the original Icon's heavy involvement.
Jack seems to have taken over security or adapted a new interest in being a sneaky peaky and watching park guests? Really the major news of the leak confirms the fact Jack will be getting a house and honestly, that gets us super excited as he officially would join Beetlejuice and Puppet Theatre and most likely the return of ToothFairy and Bride of Frankenstein. This would really be a solid start of HHN originals along with the Ghost with the Most.
