Lennon would have been horrified if he'd known what had happened to Tobias. He had a difficult time understanding people who were mean just because they could be, and he wouldn't have known what to do with that. He had his back to his friend as he started the frying pan heating and opened the package of hamburger patties, so he didn't see his reaction to stretching upward.
"Well... I dunno," he said to Tobias's question. "There were people who wanted to kick Marco out when the whole pharmacy thing happened." That had been stressful. Lennon might have been biased, but he didn't think Marco was a crappy person, more that his illness had gotten hold of him and caused him to act out like that. "Would They let us kick someone out?" Given the fact that all of them could be moved around while they slept, he had the notion that said crappy person might wake up right back in the house again the next day.
