Thor: Kirk is going to be a computer sciences major/tech things, so maybe he can help Thor with the muteness by making him up one of those electronic translator thingies? For SCIENCE! And because golden retrievers are irresistible and heck, he likes you.

Zevran: Kirk probably wouldn't mind doing some wiring or some other tech stuff for him now and then, though Kirk isn't really much of a drama person, sooooooo... he can accidentally spill coffee on him if you want a Italian blow out? xD
