not that it's all that relevant, but...

Just how long in the internal timeline has Sam been wearing that cast now? I mean, he says it's been four weeks since Ava, and he's had it for several eps before that now.

Actually I've never broken a bone myself, and I don't know how long a casts has to stay on usually, but do we need to assume that Sam reinjured it at some point by now or something because he keeps using it? (and obviously I realize that in reality it's because of external factors such as the actor being injured, but I cling to my intra-universe viewpoint)
