Mass Effect 2 - Rare dialogue - Wrex gets jealous of Grunt

Once Grunt’s loyalty mission becomes available, you are advised to ask the Urdnot clan leader for help. If you don’t bring Grunt to Tuchanka but still approach Wrex to ask him about Grunt’s problems, this is the unique (and just a tiny bit jealous) response you get from him. Uvenk also has a few words to say on that.
