to come into the merge as a spoiler. If the other tribe is starting to fraction, and they outnumber his tribe hugely, he could become a very valuable vote. They may see him as less of a threat because he doesn't have any one to allign with but them. If the the two tribes are more evenly matched at the merge, they are definitely likely to try and pick each other off. The other tribe would view him as a threat rather than a potential ally and vote against whoever they want out. Problem is, in any scenario for his strategy to work, he pretty much has to count on the fact that the other tribe is not going to be super tight.
