Kevin explained everything to them, how he had spotted the black bandage around his right wrist, the tattoo underneath, the fact that Liam was in the same organization as Alan's family and that Ashton was probably already a part of it too.
He also told them that Liam had never hidden anything from Ian and therefore Ian already knew everything.
And finally, he told them that he had invited them to dinner with them tonight to discuss about this symbol that had appeared on his forehead during his fight against the Elite Warrior Vampire.
He said that he wanted Liam and Ian to be part of their group and that Liam's knowledge of the organization would be of a great help to them, maybe he would know more about this symbol too.
And, as he had guessed, this news was well received by Alan and Erik, after all Liam and Ian were not only their friends, they were very powerful too, and they felt reassured to have them by their side.
