How significant will the character of Holloway be in this film?

Surely if he gets Shaw pregnant, and this results in something that could start the alien race, surely he'll be like a father/god to these creatures, elevating his status and importance in this film and perhaps the whole alien genre!? (the xeno's we see are effectively the baby he and Shaw made/started together). I hope this is not the case. I much prefer Shaw becoming impregnated from the SJ's when she was abducted/sweeped away to them (perhaps in some experiment? hence the 'please' bit in the teaser video), she comes back and infects Holloway, which in turn results in his transformation into some bad humanoid attacking the crew (i.e. something temporary), as opposed to Holloway infecting her. Because surely if Holloway 'started' the pregnancy then he could become a central figure to the film, second to perhaps Shaw? I don't want to see Holloway, seemingly a minor crewman in this film, become the daddy of the alien race! Just doesn't sit right with me. Opinions? Cheers
