Regarding the matter of young Kaycee being buried alive by the psycho Al Brunton – check out page 4.84 and the sequence beginning at page 4.200 (the latter in particular for instruction Kaycee received from Vostok).

As for the woman in red and black, you may remember future Kaycee becomes Maverick… first seen in Bad Karma on page 4.141… although that was also a future, alternative, somewhat battle scarred version (as recounted on 4.292)!
