Ahh, I see! :|a Even outside of the things he's been doing in Recollé, Wesker actually also has a lot of memories involving experimenting on people; he doesn't discuss them as openly, but he could be prompted to if a situation arises for it - he's not as cagey about it as he used to be, because he's coming to terms with the fact that he used to be a hideous person in his past life and being infected again will likely shake him up a little and make him more prone to talk.

So we can potentially get several memories of experimentation, either by way of physical action what with his medical things or discussion should the topic arise.
