United States on March 25, 2011. It was watched by an estimated 3.9 million viewers, earning a 1.5/5 ratings share among the 18–49 demographic, up from the previous episode's 1.3–1.4 rating. This was a 15 percent increase. Fringe helped Fox place in second for the night among adult viewers behind NBC, but the network fell into third place among total viewers behind NBC and ABC. Reviews "Bloodline" has received generally mixed to positive reviews from television critics.

IGN's Ramsey Isler also didn't find the birth storyline all that shocking "since the number of people that had the power and knowledge to do this kind of thing was low." Rating the episode 7.5/10, Isler added that "the story could have used a bit more misdirection and a red herring or two to really keep us guessing, but that's a minor critique. Overall, Walternate's Machiavellian role in this story works, and the most important takeaway from this story is that it moved the overarching plot forward in one huge leap. Instead of waiting nine 'story' months for Fauxlivia's baby to pop out, we've already got the
