Mery's torture

[liquid sword]

What kind of torture did ocelot inflict on meryl ?
was it just a simple electric shock.
or was it much more .......sinister.
the evidence that support's this idea is towards the end if you manage to rescue meryl she says.... " but through all the pain and shame there wasent a single time i"........
(what shame ?)
and this unsettling conversation......

meryl: "it wasent that bad i dident give in, to the torture"

snake:"torture"

meryl:".....And things even worse than that......I was fighting too just like you"

(what was worse)
if this suggest what i think it does .poor meryl and i dont think i like revolver,ocelot.
you thougt's plz
