the following weeks are tough for guido, as he tries to help his boyfriend come to terms with his illness. colin assumes that guido will now want nothing more to do with him, but guido assures him that he is there for the long haul. however, over the following months, major differences in the pair's political view points begin to surface. colin's liberal opinions clash with guido's more conservative ones. colin is furious when guido reports junior roberts (aaron carrington) to the police for stealing some of his cds. he feels that police involvement will only worsen any anti-social behaviour, whilst guido feels that punishment is the only way to curtail the problem. meanwhile, guido is becoming annoyed with colin's tendency to worry more for others than himself, namely donna ludlow (matilda ziegler), the unappreciative heroin addict who colin is trying to reform. their opposing opinions bring to the fore how little they share in common. in addition, colin cannot shake the feeling that guido is only staying with him out of pity and so in february 1989 he decides to leave walford to stay with his brother in bristol. colin decides not to tell guido he is going, but a surprise visit from his ex, barry clark (gary hailes), stalls his departure, and guido arrives home to see colin packed and ready to leave. guido is furious that colin was planning on leaving without saying goodbye, but colin says that he needs some space and he asks guido to look after his flat while he sorts his head out. he then leaves a perplexed guido to ponder on where he went wrong, and despite claiming that he will return, he never does.
