It's more of a legacy. Apparently, Peter David also said Kelly Hu would be in the ep, so that implies either Cheshire or Paula, or both. Haven't found the source for that, though. Maybe Artemis gets to meet the "in-laws"?

My first thought with "Bloodlines" was the storyline of that name from '93, that involved alien parasites coming to earth, and triggering the metagene in people. It created a slew of horrible 90s superheroes, the New Bloods (Argus, Geist, Loose Cannon, Gunfire, Ballistic, to name a few, and yeah, there's a reason they haven't shown up in a while).

That event could tie in with the whole Gene bomb thing from Invasion!, as well as the Kroloteans, who also like messing with genes.
