Considering that Rebecca would be in her 80s around the time that we fast-forward to in the Super Bowl episode, it's not crazy to speculate that she may not be around by then. But the show could be planting seeds for her death next — and it could happen soon, in the present-day timeline. We recently saw a flashback to when Rebecca has a cancer scare, so that could be foreshadowing health problems later. Really hoping that Rebecca doesn't go that soon, considering she's the only Pearson grandparent left.
