I believe he mentioned that he was planning on "meeting" with Guyver 1, but Guyot was his priority. And with Guyot getting away, Apollyon decided to leave.
Which Sho didn't like, but Apollyon got away.
I could only guess what Apollon would want to meet with Sho for. Perhaps it could be in regards to Apollon's overall goal.
There is one thing that has caught my attention recently. I saw an untranslated chapter online featuring a blank faced Archanfel living with the Segawa's in a small house. I also remember seeing Apollon appearing with Sho's giant severed hand, and Archanfel poking his head out of a window to see what's going on. My question is why are the Segawa's living in a house in with Archanfel in the first place?
Apollyon kidnapped them during Guyots attack on the mansion.
It seems whatever happened to Archanphel after reviving Imakarum has affected him even more, and he needs to eat and live like a human, rather than just hibernating like he has done in the past.
And I doubt Archanphel can cook very well. So Apollyon kidnapped two people he knows that could take care of him ( assuming he is who the majority of us think he is)... possibly also because he will require Guyver 1's help at some point and they have a double purpose as helpers and leverage on Sho.
As for why the Exceed Hand was there... Apollyon used Li Yentsui's ability to cut Sho's hand off after Sho had grabbed him, and teleported away with it. It kind of fell and shook the house as they were eating.
If Apollon is who everyone thinks he is how on earth did he get that snazzy armor? Supposedly it's made out of the same material as the control metal, or at least something similar. Also, am I writing Apollon's name correctly?
No, it's spelt Apollyon mate!
As for his armor, that's a good question!!
