We did. After Alec abandoned the season 2 timeline, it took a few hours, but eventually Kira saw space time blowing up, storms, massive bolts of lightning and mountains falling into the sea, and that's why she had to be sent into the past to stop their being two Alec's (in the new season 3 timeline) which seems to be slightly less destructive than there being no Alec's in the (season two) timeline. Of course... It was presupposed that Alec's domination of the technologies market is why the universe collapsed in on itself, when that can't have been true since Brad Tonkin was already active in season 2 beneath "our" radar which means that Alec was Jack Shit important to the Future more so than Carlos when his absence caused the space time to implode. Alec was not important. Alec's departure caused the universe to die. Therefore the universe cannot cope with any players of any pedigree being removed from it's planned sequencing.
