Then Momo decided make things official and Varg shrugged and said; "Hey, not bad idea. Get her registered so she is not snatched from us. Dressed like that most think her as slave anyway." Varg saw that Tewi may lil bit missunderstand the situation but he let her take the bait. If making her official slave for the group just solidfies her position legally speaking. Also it helps keep her out from trouble or getting lost, as despite how good fuck she is she is also decent in a fight and help disabling foes which Varg can chop down with his axe.
