Seibel, therefore, "cannot bring derivative claims on behalf of [Rare] without joining [Rare] as a party to the suit." Mazzio, 2014 WL 2866040, at *5; cf. Gephart v. Merryman, No. 18 Civ. 1670 (GMN), 2019 WL 208857, at *4-5 (D. Nev. Jan. 15, 2019) (holding LLC indispensable and dismissing case because LLC's presence destroyed diversity). And it appears undisputed that Rare's presence in the suit would destroy diversity: Rare is an LLC, and the citizenship of an LLC is that of each of its members.
