Based on 1x04: Penelope is super nervous about going on a date for the first time in fifteen years so instead of setting her up with a guy Schneider offers to take her out to dinner so they can pretend to be on a date and hopefully calm her nerves. At first she's kinda dismissive of the whole concept, but what the hell it's just Schneider right?
Based on 1x13: Honestly I just want Schneider taking the Alvarezes home after Elena's quinces, helping put the kids and Lydia to bed, and then Penelope going up to Schneider's apartment to check if Victor is really gone (he is) and then I want the two of them to sit down on the couch and just unwind, maybe she puts her feet on Schneider's lap, maybe they end up making love on the couch, just. domestic Alvereider enjoying each other's company at the end of a long night
Based on 2x5: Something something panic room, like maybe the kids and Lydia are actually out and Penelope is hanging out at Schneider's instead of waiting for Max, so when the lock down starts they both end up locked in together in Schneider's panic room
(Might add more to this post as I go)
