I don’t know what inspired that particular photo shoot, if it was his idea or the CW’s, since it happened shortly before The Flash premiered its first season (not a year ago; he was prob just doing a throwback to it to promote the photographer). It doesn’t make sense to me why it was Danielle and not Candice either (aside from racist crap). As far as Grant not doing one with Candice ever or anyone else? Grant is not very pro-active in promoting himself. More or less he only does photo shoots if he feels they’re absolutely necessary. These last couple shots he did w/ Tyler was the first he’d done in YEARS - minus the s3 crossover shoot w/ SA & MB. But even if that wasn’t an issue, I’m pretty sure he still wouldn’t do one w/ Candice given how messy & suspicious their relationship is at times. Grant’s body language gives him away time and again, and that’s all a photo shoot is. I will be shocked if they ever do a shoot together. But I will be equally surprised if he ever does one with DP again. Barry’s love life had different directions it could go in back when the show was starting, even if he never saw Caitlin that way. Now the audience has to be informed via dialogue they’re supposedly bffs b/c they rarely have scenes together to prove that, so it would feel out of place if they did a shoot together to promote the show again. Only Candice would make sense, or the whole team, or the Big Bad of the season. Not the actors to two characters who hardly interact solely.
