				Using the same cells in the skyscraper
 
 
Either  r4c4 <> 6 as then no 6's in box 4
 
or r5c23 <> 6 as then no 6's in row 4 |

If you put a 6 in r4c4 aren't we left with a 46 pair in r5 (box 4) ? |

This is what I saw
 
 
If r4c4 =6 then r9c6=6, r5c8=6 ==> no 6's in box 4, but if you travel a different road you will see something else! |
