I think the answer is simple... The QA.
The QA's job right now (Though it seems that they may not even realize it) is to kill the GR, so that the Illusionist Evolves into the Yeti. So, since the QA is hunting the GR, it would make sense that.. since the GR couldn't lynch you (b/c you came out) AND didn't push to lynch the defender (as I had hoped s/he would) then the GR should be going after the one hunting him/her at night.
Because pretty much everyone thought that LIS was a QA, then the GR was probably voting for the QA. Of course we can't be sure, but that would surely have been the best move.
There is, of course, another possibility. Though I am not going to discuss it. B/C the strategy may not have come up yet in the minds of the baddies...
