Lemoine is trying to make the case that Vic knew, at the time he filed the suit, that the texts from Ron were not the proximate cause of Slatosch's breach. That's a stretch, but not a huge one. Slatosch's affidavit says he got the texts, but he also says that he didn't cancel until after other VAs than Monica started dropping out. That's an inroad to arguing that there was an intervening cause. I wouldn't waste my time on it, but if Lemoine wants to that's up to him and the judge. At the very least, it is an unexplored avenue.
"Very frivolous" would be asking for a deposition of Huber. Huber's affidavit didn't really go to any issue that it is worthwhile exploring. The guy didn't know anything relevant to the case, he just knew the people involved and had heard a lot of rumors. Yeah, he made Rial/Toye look like buffoons, but that's not depo worthy.
