I’m probably thinking too much but if in S5 in the future say timeline A Fritz can’t appear from being frozen? In timeline A Fritz went out with others somewhere between the Earth was destroyed and the Skrull enslaved humans in a space station. While the others say from timeline B (which is the main timeline) could be sucked into future timeline A (from timeline A as present’s perspective they were from the past history) by timeline A alien Enoch via that meltable slab (a conduit like the launch pod in EG), then timeline B Fritz won’t wake up to timeline A naturally without any inter dimensional travel conduit because the Earth remains intact in timeline B. It’s like the old Cap in EG who didn’t go back to the main timeline past and grew old to the present, he somehow went back from the alternative timeline after spending most of his life there to the main timeline?
Okay I’m thinking too much.
