but getting to look through 
his library is a big win for me!
aber der freie Zugriff auf seine
Büchersammlung ist einfach Gold wert.
pero salí ganando,
puedo ver su estudio cuanto quiera.
pero a mí me ha venido de perlas

mais moi, ça m’arrange.
Je peux profiter de sa bibliothèque.
ma poter curiosare tra i suoi libri,
per me, è una gran vittoria!
só que dar uma olhada na biblioteca dele
é uma grande vitória para mim!
но я только рад вволю покопаться
в кабинете старика.
