Have Sollux and Aradia ever met in person before Aradias death (not counting when he killed her)? And what did Sollux mean when he said to Aradia in front of the Green Sun that he could only see 2D, could he see her or anybody at all?

They’ve probably met given Aradia said “ He surely would have told you if he was making the trip all the way out here from his hive stem

And when Sollux said he could only see in 2D he meant that he was blind in one eye so he had no depth perception.

After Sollux was first knocked out from the fight with Eridan, wasn't he completely blind? If so, how did he go from that to half-blind?

Okay, this is kinda difficult to explain, so there was blind sollux and a ghost sollux and when blind Sollux died the two kind of merged into a half-ghost Sollux that was blind in one eye. And then pre-retcon the ghost was sucked out to make Erisol so then he was 100% alive but entirely blind. 

We don’t actually know how that works, it probably has something to do with him having two dreamselves.
