Yeah. We tolerate all kinds of stuff as shown through special effects that we tend to go "EEP!" about when it's shown for real. See, e.g., ISIS beheadings, burning people alive, etc.
What we have here is a likely-fatal ritualized draining of two hapless captives of their blood, followed by a shower of same over a naked, exulting Omir. Considering that this is (fictionally) ACTUALLY HAPPENING, this is not merely TV-PG.
BTW, this isn't terribly surprising, but I notice he's got himself a capsuleer rig. Sockets all down the spine.
