User blog comment:ItsAlwaysSunnyInIllium/Do you think Ashley/Kaidan will be in Arrival/@comment-1221773-20110318185645

The thing you've got remember about LotSB is that it isn't some stand-alone story. It ties directly into the whole ME: Redemption comic mini-series. Ashley/Kaidan don't have that going for them.

While A/K could appear in Arrival, I think it's unlikely. Even if they do appear, they'll be little more than side-note to Arrival's "the Reapers are coming" plot. If we ever see A/K again, it'll be in ME3, and probably with a larger role.
