Right now this does not make sense. As others have stated, Magik's powers make this whole trip seem kind of pointless. Plus taking both Doug -the guy who communicates with their island home - and Illyana - 1 of the 4 generals in charge of defending all of mutantdom - just to finds Sam and give him the good news is just plain stupid on Xavier's part. It makes me wonder what the point of making Illyana a captain in the first place was. Though to be fair Bishop also seems to have nothing to do as a captain right now, so I can only assume that will come into play later when Krakoa is truly threatened. Still hoping she and Doug at least have another reason for coming along that will explain things even if the rest of the gang is just there for Berto and Sam.
