There was a saying that someone's trash is someone else's treasure.
But it seems, it is also held true for the saying someone's heaven is someone else's hell.
After Lucas dropped the bomb, at first Vanessa was too shocked to speak to the point that she remained frozen for a few moments, scaring the shit out of Lucas and Leonard who thought that she might have had a heart attack.
However, as she recovered, Vanessa showered Lucas with hugs and kisses filling him with love and congratulating him happily with tears.
She looked genuinely happy for Lucas' success.
But.....
It seems it was only true in the case of Lucas as Leonard was subjugated to an immense round of beating and brutal assault. It did not leave any wound physically but it mortified his soul engraving it with fear.
