Wrex likes the Krogan Monument; it seems much more impressive to him than the Relay Monument. If Commander Shepard speaks to him in front of the Monument, Wrex soberly says the statue represents the values of the krogan – honor, loyalty, courage, fortitude – which have now been lost to his people since the Krogan Rebellions and the devastating genophage. Either human squad member and Liara will comment that Wrex really isn't like other krogan; Wrex shrugs and says "I'll take that as a compliment".
