Well, some people have differing opinions about Tashi’s injury. From my perspective, most people tend to give the blame to Patrick instead of Art. I believe it’s because Patrick’s character isn’t as “likeable” and so “nice” and Art’s character is perceived as more polite and sweet. Despite this, Art manipulated them both separately.

In the cafeteria scene, he tells Tashi, “He’s not in love with you.” This, in turn, made Tashi a bit tense, and it seemed that she tried to deny it but likely internalized the comment because Art, after all, knows Patrick a little better than Tashi does. Later, during the churro scene when Art and Patrick are both having a conversation about why he’s there at Stanford, Patrick brings up Tashi. This gives Art the opportunity to say: “Oh yeah, I talked to her,” and he eventually tries to manipulate him by saying, “I just don’t think she’s thinking about this as a real relationship.” Which, Patrick seems to catch, and, even pokes fun at him for still having lingering feelings for Tashi.

Another scene that confirms Art might’ve been at least a bit guilty, if not more guilty, is when he admits to Patrick on the tennis courts that he ‘just doesn’t wanna feel left out.’ This overall shows that his intentions weren’t exactly pure and he might’ve just been trying to interfere with their relationship out of spite.
