Tom has shown how competent he is, as he also demonstrated holding down the forte at ACN
when Logan's funeral was happening. I think our thoughts on him are sometimes coloured by the comedy act with Greg but arguably yes, he is one character who has developed and showed a degree of self-knowledge and ability to navigate, the siblings sorely lacked.
Spoiler
Matthew Macfadyen has proven to be one helluva actor, in this company too.
