Not only have they already found evidence of the Borg back in the Alpha Quadrant, now there's the additional mystery of who or what created the subspace rupture. Icheb's got his work cut out for him, and the fact that all he's got with him is a tiny Saber
-class ship doesn't bode well if the Borg make another appearance.
I especially liked the segment where Captain Oyugo reflects on her relationship with Icheb. Though she still harbors reservations about her exec based both on his youth and his former Borg status, she's determined to make the best of things. Given his skills and knowledge of the DQ, that's probably for the best, though I'm hoping the decision doesn't cost her in the long run.
