How will Finn Balor and Brock Lesnar interact?

Finn Balor is set to take on Brock Lesnar for the WWE Universal Championship at the Royal Rumble in one of the most anticipated match-ups on the card. The build-up to this match has been rushed, to say the least.
Until last week, it was Braun Strowman who was set to face Brock Lesnar. Finn Balor had an absolutely star-making performance on Monday Night RAW last week, openly defying Vince McMahon, and going through John Cena, Baron Corbin, and Drew McIntyre, en-route to setting up his bout with Brock Lesnar. However, Finn Balor still hasn't interacted with either Brock Lesnar or his advocate Paul Heyman?
What will happen when these men step into the ring? Will we see the appearance of The Demon? Will Luke Gallows and Karl Anderson reform The Club alongside Balor?
So many questions. And no answers.
