Me too. Even in the flashback episode all we got was one-sided Michael being angry and a snide remark in response from Lincoln. I really want to see some actual, serious arguing. Especially with how derailed Michael's become all in service to The Plan - that's got to be freaking Linc out a bit. I really, really want to see Linc lay into Michael for hurting himself, getting himself sent to the psych ward, and not even letting Linc know so that Linc was left to worry.

Though I can't really think of how they'd even be able to get close enough to yell at each other, since Linc is still stuck in solitary.
