At some point, Karen and Ted Wheeler bought or inherited the house and began living there with their children. This house was likely an attractive option for a family home, as each child could have a bedroom of their own.
The next day, Karen announced that neither Mike and Nancy were to leave the house without her permission, as she was concerned about their safety following Will's disappearance. However, Nancy made up lies and excuses to get out and see her new boyfriend, while Mike found ways to sneak out unnoticed.
After Mike and his friends found Eleven, they let her stay in Mike's basement. Mike regularly provided her food as she stayed at his house as well as accommodated Eleven by skipping classes. Eventually, they grew fond of each other and formed a strong bond. When Will was presumed to be dead, Eleven convinced Mike that Will was still alive by channeling him through the Supercom from the basement. However, the Department of Energy quickly tracked her down and arrived at the Wheelers' doorstep, forcing Mike, Eleven and his friends to escape. Meanwhile, the Department of Energy questioned Ted and Karen as they searched the house for evidence relating to Eleven.One month later since Eleven's presumed sacrifice and Will's return, Mike and his friends hosted another campaign of Dungeons & Dragons in the basement. As the campaign and the medal ceremony concluded with his friends returning, Mike longingly stared at the pillow fort. After Eleven's disappearance, Mike, who clearly missed her, had been keeping Eleven's basement pillow fort in perfect condition in regards to her memory.
Even since Eleven's disappearance, Mike had been attempting to contact Eleven using his Supercom every night at the basement.
On day 352, Mike, as usual, went to the pillow fort and attempted to contact but to no answer. But as he started walking away, he heard a brief crackle of static and thought as if El was saying his name. Though upon replying back, he found out that it was Dustin and got disappointed.
Mike brought Will back to the Wheeler's basement after he experienced another vision of the Upside Down. Will explained Mike that he felt stuck in between the real world and the Upside Down and saw a large shadow that tried to catch him, but requested Mike not to reveal it to anyone.
On day 353, that night of Halloween, Mike attempted to contact Eleven from the pillow fort again, but this time, Eleven was also simultaneously visiting him on her mental void. Mike, unaware of her presence, revealed that he'd been trying to contact her for 353 days and wished that she was there. However, before she could make contact, Mike left.
