There are some really great moments but this page is one of my favorites. Actually the whole issue, UXM 308 is.
It's not their most iconic moment, or the one people will remember first but it feels real. This issue captures a mature Jean and Scott, who are going into marriage understanding what that means. They both brought their well earned doubts and insecurities into this issue, mostly Jean. By the end of the issue they realize clearly just how powerful their history and connection is, and decide that life is too short to allow fear to keep them from what they want.
Not exactly puppy love, but that's exactly why this issue matters to me so much. DPS was great and all, but for me X-Factor 53, UXM 308, XM 30, AoC&P and SfC are the issues that frame their relationship best.
