Part of Walker wanted to meet the tamer that Onyx had mentioned. Being able to speak to a tamer that specialized in giant anacondas would be a wealth of information that might be able to help him understand some of Onyx's needs in the future. Only was still fairly young and only grew so fast because of the things they had experienced. Being able to have the tips and tricks might help Walker when Onyx needed help most.
There was also the fact that a tamer that was obsessed with snakes and serpent type monsters could be a good ally to have. There were a lot of serpent type monsters nearby because of the swamps and the grass lands. Let alone when Walker went to the mountains, which was more often than he would have expected.
"Brother, what do you have planned now?" When Walker returned to where Alice was sitting, Onyx asked him for his plans. Walker was ready for this though. He wanted to invite the high priest and Alice to dinner as well.
