Let`s analyze Tybalt as a character
A person of extremly low character,I see Tybalt as someone who would stalk someone - he is stalking Jill despite being ignored religiously,not just by Jill herself but pretty much everyone,except for his group of very low standards,someone like Tybalt just can`t stop himself and keeps going,that is pathetic.I can see him stalking MC at some point,seeing MC has something that he wants...-attention,attention of someone Tyty values,feeling safe on the internet Tyty would actualy report the MC

on a public forum that Rooster is,can you imagine?When you thought this guy just can`t possibly be any lower,well he does deliver

I think Tybalt noticing that MC,again,has something that he wants would(or already is)obsess about the MC,he would try to provoke,to get any reaction,again,pathetic.Seeing the MC cares about some other girl than Jill,Tyty could try,to hit on that other girl,despite not really liking said girl or at least copy MC`s desire to have kids with said girl,just proving once again of how LOW character Tyty is.Personally I see no value in Tybalt whatsoever.
Therefore I give Tyty the lowest of cards
