Checklist:
1) Not a hologram.
2) Old but energetic-looking.
3) We're allowed to call him John Ellicott (which to me sounds much better than John Ellicott-Chatham for some reason)
4) Technology jokes.
5) Doesn't seem to be that distanced (at least emotionally) from his daughter.
I think Jeph just created the perfect Hannerdad.
Ok, now that that's done, deeper analysis time.
Marigold only appears in one panel of today's comic, and even then, only to show that she is there. This indicates that her sense of shyness in the presence of famous people hasn't got that much better since
her nosebleed at the comics convention. Marten, for example, is right next to Hannelore the whole time, and takes the time to wave and ask questions, whereas Marigold just stands there with her hands at her sides. I'm not even sure where she's supposed to be relative to the others in the last panel.
As for John Ellicott (and I will
never get tired of calling him that), he seemed quite initially distracted and surprised to see Hannelore. I'm not quite sure what this means; he could just have been really distracted by rummaging to find his mp3 player, or it could mean Hannelore had a fairly wide window of opportunity to get to the space station (i.e they weren't expecting her at any particular time). Or
perhaps he could have slightly forgotten that she was coming, since he was so wrapped up in his work. But probably not. He does seem quite close to Hannelore on first impressions; it's not like he was saying "Just a minute, I have to find my vitally important mp3 player before I can attend to my daughter".
