It's not known what Vesser's crime was before he got sent to SAR TOP. After taking on a human form, Vesser was sent by Zin to negotiate a deal with Nestov - in exchange for certain equipment by the next day, Nestov would be paid $10,000 - the first $5,000 been paid in advance. Nestov - first commenting on how Vesser's human form looked better then his 'usual' self - refused the money, cracking jokes all the time during his conversation, while asking questions about 'getting in' and helping Zin's operation. However, Vesser tells him that Zin already has 'the best' - referring to a female Desserian called Zareth, whom Nestov calls 'a legend'.
