I'm not worried about Dr Boring at all. I don't see him as a threat in the same way that Rebecca is. She actually succeeded in her efforts to split Robron up, but we know the Dr is only in a handful of episodes, we know he can't get pregnant and force us to watch 9 months of a storyline from hell and we know the Robron reunion is soon. Plus as Robert sees the kiss, it's obvious that it's just a plot device.
All of this.
Legit the spoilers are like what will Robert do? Something crazy as per.
