What part of the ending imples the catalyst survives? In control you replace the catalyst, in synthesis you reach the catalyst's long term goal so it stops and in destroy you force shut down the catalyst and hence the collective intelligence of every reaper hence they all die (probably insert something about reaper code to explain why the geth and edi die too). I cannot for the life of me find in my memory where the bit that imples the catalyst escapes is.
