One of the infamous sequence of numbers from 'Lost' (4, 8, 15, 16, 23, 42) appeared in this week's penultimate episode of 'Heroes'.
Mr. Linderman told Nikki/Jessica and DL that their son Micah was being held on the 42nd floor.
The number '23' showed up in an earlier episode when Mohinder was in Bozeman, Montana. That was the number of his motel room.
There has been talk of some kind of connection between 'Lost' and 'Heroes', but it was definitely confirmed when Jessica used Gannon Car Rental to get her to L.A. for a contracted hit on one of Mr. Linderman's foes.
But there was also a suggested one when Nathan talked about what would happen if the "heroes" went public with their secret - that they would be whisked away to some island in the middle of the ocean where experiments would be conducted on them in underground laboratories.....
