I think the only way they don't have another encounter is if the run ends before its supposed to. To me this is a clear set up of another showdown. This was like Darth Vader killing Obi-Wan Kenobi in front of Luke to set up the later showdown between the two of them. Outside of Robinson leaving the title earlier than anticipated or whatever and a new creative team going in a completely different direction, I'd be outright shocked if they don't legitimately thrown down.
