Dawkins is actually excellent at sewing, but he's never told anyone about him doing it due to such a hobby being considered "effeminate." However, Dylan would probably know about it due to having walked in on Dawkins sewing up a new little outfit for Princess Positron. 

Dylan: Don't they sell pre-made outfits online?

Dawkins: Well, those "outfits" are all mass-produced, look horrible, and fall apart within days! And truly someone of such brilliance and benevolence deserves so much better in terms of apparel. Isn't that right, Princess?

(He pulls her string.)

Princess Doll: Positronly!

(Dawkins hugs her.)

Dawkins: (whispering to Dylan) Also, between you and me, pawmade clothes are much more cost-effective.

  Now that Princess Positron has been destroyed, however, sewing is more likely to just make Dawkins break down in tears.
