My thoughts were along the same lines as Songbird's regarding Trask. Then my mind went evil, as it sometimes does, and Ultrawoman showed up.
There is obviously something planned and Kal-El sounds prepared for public acceptance or resistance. Ultrawoman would be a wildcard. Could be friend, foe or anything. Whether the powers were Resplendently duplicated or Ultra transferred it would put a little chaos in Clark's life. And if they were transferred, then he would have the same chance of discovering Ultrawoman's identity that Lois has of discovering his.
As they said in Maxwell Smart, "Verry Interesting"!
