I like Sara, so it was kind of bittersweet. Spoiler: next week Next week's promo and pics make me hopeful.. my favorite three CSIs working together! On his wikipedia page, it says that "In 'Ultimate CSI' Greg's name is printed as 'Gregory Hojem-Sanders.'" It seems like his parents/mother hyphenated their last names, rather than dropping it completely, and Greg has dropped it now - so his grandfather is calling him by the more familiar part of his last name? Also, if his grandfather's first name is Olaf - why is his grandmother 'Nana Olaf'? I'm totally confused now, so I think I'll just ignore it and pretend it all makes sense.
