Alex's mum Candace. She's not at all well (certainly not enough to work), but she's not going down without a fight.

They share a flat. The majority of it is pictured. Thankfully, given this proximity, they get along pretty well (that is, the shouting is much more likely to be at some goddamned politician on the TV than him).

Candace pretty much insisted that her bed come out here and Alex have the bedroom because it's 'more sociable', but it's possible she's just trying to give him have some privacy.
