Hello! This scene can likely be tightened up a fair bit, so keen to know any specific notes you have. But have you told Ana what WBE actually stands for? With a certain other piece of key information you should be able to progress....
Viewing post in Stuck on Beatrice Abbot dialogue route?
I was so happy to find out what WBE is meaning but I have absolutely no clue how to progress from here. You should give a few more hints inside the game. The web is big and you could basically search for everything ... also those names you chose are not really rare.
Edit: I also got the farewell email but the only way to get things progressing was to type "hint" in which moment Ana realized what she found out ... strange.
